Placebo for sure. It does not work. The pills is a way that the company can hook you in for weight loss coaching. The pills actually don't do anything for weight loss. I took them for 90 days as directed. I exerise regularly. I did not change my exerise or diet because as the advertisments continually say is that you will lose weight while eating what you want and not having to workout a bunch. Pretty sure the powder in the pills is simply vitamins. Do not waste your money

The more wavelength-specific light is blocked, the higher of it. For instance, laser safety glasses will completely block all but.00001 percent of the laser wavelength at an optical density of 7. Most medical facilities advise using optical density laser safety glasses with an optical density of five or higher when working with medical equipment.

I clicked on the Fitspresso ad on You Tube and patiently watched the 30 minute video which was very good explaining their scientific research about being able to eat, not diet, and still shed unwanted fat cells for weight loss. While the sales pitch was winding down, I started to check reviews. It was difficult to find a review that was not attached to a Fitspresso site so I am happy to find reviews here at Trustpilot.Thank you all for your input. I was a nano second away from hitting submit. I was glad to read, for the most part, their customer service honored the advertised refund policy.So, I will continue to adhere to that old adage, if it sounds too good to be true, it probably is, and check reliable reviews!

Whether the light wave accelerates or decelerates when it crosses the border determines whether a beam of light will tend to bend in one direction.

Anyone can write a Trustpilot review. People who write reviews have ownership to edit or delete them at any time, and they’ll be displayed as long as an account is active.

The optical density measures how much a material or object lessens the intensity of light passing through it. Light may pass through a medium more slowly the more optical dense it is. The average one of it and area of each fiber are measured.

A lengthy, quite boring video for yet another weight loss product that doesn’t work. I hope the scammers behind all this nonsense can sleep at night. Their bank balances will look good for a while until everyone who believed the bull**** stops paying them, then they’ll move on to some other money making scam, the desperate are easy prey after all.

The process by which light or other electromagnetic radiation passes through matter is called optical density. The wavelength of the radiation, which involves interactions between elementary particles like electrons, atoms, and ions, affects the emission and absorption processes.

The optical density of an object measures how much light it absorbs and how much light goes through it.It is used in research and engineering to determine the materials that make up an item.

The product doesn't work. I ordered 3 bottles and received 9. After 6 weeks of using fitspresso I returned the remaining bottles. I followed their specific directions for return. That was back in March 2024, still no credit. I was stiffed for $338.

Offering incentives for reviews or asking for them selectively can bias the TrustScore, which goes against our guidelines.

The characteristics of the medium affect a light wave’s speed much like any other wave. When an electromagnetic wave is present, the optical density of the material affects the wave’s speed.

It is used to prevent eye damage in the laser business, which employs Class 3b and Class 4 lasers to create the eye. Class 4 lasers have enough power to harm the eyes permanently. Additionally, these lasers may result in skin burns and fire risks. The light’s wavelength influences its eyeglasses. As a result, the eyewear is evaluated according to the amount of light it reflects.

Optical density definitionMicrobiology

The ratio is carried out at the absorbance ranges’ peaks since there is a low likelihood of absorption with a transition in wavelength. Numerous crucial factors, comprising cell concentration, biomass production, and many more, can be quantified using this strategy often.

Although both estimations of how much light is immersed as it passes through an optical medium, optical density and absorbance are different.

Optical density definitionPhysics

Its laser glasses quantify how much of the light transmitted from a specific wavelength is blocked by the lens of the laser safety glasses.

Refraction is the path of a light wave being bent when it travels through one material and then another. The light wave’s altered speed as it crosses the border is what causes the refraction to happen there.

I'm sorry to the people who bought into this scam but if you watch the whole video the person who was talking about it was a patient, So how come she is selling it and she keeps saying we are selling it not just the doctor. So please listen to every word that's being said in these ads that how I knew it was a scam. Be careful folks.

The optical density of a substance is related to how slowly its atoms tend to hold onto the energy they have absorbed from electromagnetic waves in the form of vibrating electrons before remitting it as a fresh electromagnetic disturbance.

I ordered and never received my order. I have called several times and they said different things. I received an email to say it was delivered, and when I called, they said it was in process. The next time they said it was delivered. Then the the next call, they said they were sending another order. I never received the second order. I requested to get a refund and still waiting for me refund and I believe it is a scam.

Be very wary of this product because it contains nano technology. When I emailed in the staff who replied they didnt answer my questions and do not seem to have any awareness of what it is they are actually selling. Another red flag.

It is repeatedly contended to be the same as absorption. The percentage of radiation that is endorsed through a matter to radiation that is declining is logarithmic.

The decibel loss in transmission equals the ten times loss in optical density. For example, an optical density of 0.5 denotes a 5dB loss in transmission.

A medium’s physical density is different from its optical density. A material’s mass-to-volume ratio is referred to as its physical density.

The video for this product that shows Jennifer Aniston is not even real. Someone else's voice has been modified to appear that Ms. Anniston is talking, but it is NOT her. Look closely and you will see that her lips aren't coordinated with what you're hearing. What she is actually talking about is adding collagen to her coffee every morning and how it helps to metabolize carbs. This technique of piping in a celebrity's voice is a newer technique being used to deceive people into buying products. READ ALL THE REVIEWS here!

There are thousands of successful people who don't see these reviews. I think you should give Fitspresso a try. They have a 180-day money-back guarantee.

Light bends because of its decreased speed. The concentration of light caused by optical absorption affects it. The matter’s optical density will rise with higher concentration.

I tried FitSpresso and it was not effective for me BUT I contacted FitSpresso Support. They were very kind, professional and prompt. They gave me options to satisfy my dispute and ended with offering a refund. I shipped the product to them and they sent an email that I’d have my refund in short order.

I came real close to buying the 180 day supply, however the whole time I kept saying, she said she has a wonderful husband name Scott. Then why isn’t she wearing a wedding ring. I realize this was a set up and she doesn’t have a husband named Scott. The whole thing is I’m sure a lie. Yes, I know not everyone wears a ring but that Little glitch made me check into it further, and I did not like what I saw.

It is appreciated you have shared your experiences, which helped me not to purchase. It's the public that can stop this from continuing. The government (USAgov) should be made aware so they can launch an investigation.

The medium with the highest refractive index has the largest one and vice versa. So, according to that, Diamond and air have the highest and lowest refractive indexes, respectively. As a result, diamond has the highest it, and air has the lowest one.

When there is very limited light transmission through an optical filter strongly obstructing, (OD) can be used to define the transmission. The slower the wave moves through the material, the higher of it.

I bought, it more accurately was duped, into purchasing more than a year’s supply. After 5+ months of using the product. I realized I’m not getting the benefits promulgated in their website videos. I contacted their customer service to get a return authorization based on their No Questions Asked moneyback guarantee. I was told that my purchase was just beyond their six-month limit and they will not honor the guarantee. I would avoid doing business with this company.

We may better comprehend the exhibition of it and how it influences light passing through it by differing the two media.

After using FitSpresso, I can say it’s the best decision I’ve made for my health. The results speak for themselves – I’ve lost a noticeable weight and feel great! Thousands of people, including me, are seeing real successThis product has been on the market for over 4 years. If it wasn't good, it would have disappeared. I think you should give Fitspresso a try.

FitSpresso has been a lifesaver! I’ve lost weight without the struggle, and I’m so happy with the results. It’s a fantastic product with an unbeatable guarantee, so there’s no reason not to try it.The negative reviews here may be because results vary from person to person. Thousands of people have lost weight successfully and don't see these reviews. I think you should give Fitspresso a try. They have a 180-day money-back guarantee.

Think about the factors of glass and air, two various media. The speed of light declines as it departs through the glass from the air. As a result, the light reprobates from its particular path.

The optical density of the material determines the speed of an electromagnetic wave. A material’s mass/volume ratio is referred to as its physical density.

In the context of laser safety, the fraction of light that is attenuated by the lens at the certain wavelength being measured is known as optical density (OD).

This was a total waste. They sent the product, which you don’t need to take coffee but that’s how they sell its success. However, they immediately tried to sell me a personal weight loss councillor for $1200.. not impressed at all

This is how materials transmit light or other electromagnetic radiation. The emission and absorption processes are affected by the wavelength of the radiation, which involves interactions between fundamental particles such as electrons, atoms, ions, and so on.

Optical density is still often used. Nevertheless, to predict the level of safety, a person must have to work topic kinds of lasers in occupational health and safety contexts.

Oh thank you Trustpilot and all you wonderful honest folks who left reviews! I, like so many other desperate people almost fell prey to this scam! Gotta hand it to the scammers, the actress was super convincing, even had me in tears at one point. These guys are good. They know exactly which buttons to push for an emotional response that makes you feel connected to the seller! So glad I remembered to always do my research, got out of the emotional response and didn't pull the trigger on these!

Seems a little weird that the reviews are mostly one star and 5 star reviews which weird there’s very few in the middle. The long videos that don’t reveal the product until the end are usually a scam. I’ll use my money for my gym membership on this one.

Engineers and scientists can use it to learn more about an object’s qualities, such as the components and properties of the oil, or in the medical profession, look at bacteria and proteins contained in a cell.

Optical density relates to a material’s capability to prevent a certain type of light. Despite being assumed by parameters that may be calculated in specific quantities, optical density has no dimensions and no connected scientific unit.

Since optical density and transmittance are inversely related, the larger the optical density, the lower the transmittance.

I haven’t tried it and won’t. It’s to shady. If it were me and the product was that good you should send out the first 30 day supply for free, just charge shipping and handling. If it really works they would be begging to buy it at $60.00 for 30 days, and would be telling everyone. Just my thought!

One medium is said to be different and the other to be heavier when light refracts through them. The term different and heavier medium is, therefore, comparative. A different medium has a higher speed of light, whereas a heavier medium has a lower speed of light.

I've had amazing success with FitSpresso! After using it for a few months, I lost significant weight and feel healthier than ever. The 180-day money-back guarantee gave me confidence to try it, and I’m so glad I did. Thousands of others have experienced similar results, shedding 60-28 lbs in 3-6 months. I highly recommend FitSpresso to anyone looking for a safe and effective weight loss solution!I don’t understand why there are so many negative reviews about FitSpresso. This product has been on the market for over 4 years. If it wasn’t good, it would have disappeared by now.

Scientists can tell which species, such as bacteria, are developing within the cell based on how much light enters. High bacterial populations alter an object’s optical density, preventing light from flowing through it. More light may get through cells with fewer germs.
