X-ray: X-rays can be used in many instances. For example, a doctor can use an X-ray machine to take an image of our bones or teeth. Airport security personnel use it to see through and check bags. X-rays are also given out by hot gases in the universe.

Gamma-ray: It has a wide application in the medical field. Gamma-ray imaging is used to see inside our bodies. Interestingly, the universe is the biggest gamma-ray generator of all.

Infrared: It is used widely in night vision goggles. These devices can read and capture the infrared light emitted by our skin and objects with heat. In space, infrared light helps to map interstellar dust.

Electromagneticwaves

The entire range (electromagnetic spectrum) is given by radio waves, microwaves, infrared radiation, visible light, ultra-violet radiation, X-rays, gamma rays and cosmic rays in the increasing order of frequency and decreasing order of wavelength. The type of radiation and their frequency and wavelength ranges are as follows:

In cases where light with continuous wavelengths passes through a low-density material, the atoms and molecules of the material will absorb light waves with the same set of characteristic frequencies. This results in the production of the absorption spectrum, which is a nearly continuous spectrum with missing lines.

Ultraviolet: The Sun is the main source of ultraviolet radiation. It causes skin tanning and burns. Hot materials that are in space also emit UV radiation.

Lepro products have cuttable mark on LED strips. Just cut off the excess at the cuttable mark.Usually, it could be cut every 3 LEDs.

Radio waves have the lowest frequency and, hence, have the least energy. E = hf E = Energy f = Frequency h = Planck’s constant

Answer: No, X-rays and gamma rays are short-range. Moreover, they are harmful and have penetrating power on the matter with which they interact and can damage the tissues of living bodies.

Lepro offers a huge selection of single-color strips and multi-color strips in our LED strip lights (RGB or RGBW). Warm white, neutral white, cool white, red, green, blue, yellow, pink, and other colors are all available. Different hues and color temperatures elicit various mood-altering atmospheres. Warm colors, such as orange and red, induce feelings of vivacity, elation, and excitement; cool colors, such as blue and green, induce feelings of tranquility, serenity, and steadiness.

Visible light falls in the range of the electromagnetic spectrum between infrared rays and ultraviolet rays. It has frequencies of about 4 × 1014 to 8 × 1014 hertz (Hz) and a wavelength of about 740 nanometers ( 2.9 × 10−5 inches) to 380 nanometers (1.5 × 10−5 inches).

The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 1025 Hz, corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves. Generally, in a vacuum, electromagnetic waves tend to travel at speeds which is similar to that of light. However, they do so at a wide range of wavelengths, frequencies and photon energies.

If you want to install the LED strip lights indoors in your bedroom, living room, or all around some furniture, you don't need the waterproofing feature. You can simply purchase non-waterproof LED strip lights; this will also reduce your budget requirements. If you want to install strip lights in your kitchen, bathroom, or other areas where there are frequent splashes of water, we recommend purchasing lights with an IP65 rating. If you are wondering whether you need to acquire strip lights with a protection rating of IP67 or even IP68, there isn't much of a need for that (unless you're continually submerging the strip light in water, which is normally uncommon indoors).

Radio: A radio basically captures radio waves that are transmitted by radio stations. Radio waves can also be emitted by gases and stars in space. Radio waves are mainly used for TV/mobile communication.

Radio waves

The electromagnetic spectrum, in simple terms, is defined as the range of all types of electromagnetic radiation. We shall learn about the concept in detail and understand all its underlying aspects in this lesson.

Question 5: A ray from the sun, passing through your kitchen window, hits a prism that casts a rainbow on the windowsill. Supposedly, there is a hand-held radiometer on the table. Now, you place the instrument on a specific colour of the rainbow with your eyes closed. When you open your eyes, you see that the radiometer measured the energy from that colour at 4.0 x 10-19 joules. If we take Planck’s constant of 6.6256 x 10-34 joules/sec, what possible colour did the instrument measure? How can we determine this?

1. Lepro products come with ultra-strong 3M adhesive. LED strip lights can be firmly stuck on anywhere you want.2. Support clips are available for stronger fixation.

● The radio waves and microwaves discovered by Hertz paved the way for wireless television, radio and mobile communication.

We can learn about a substance by analysing the EM spectrum given by it. When light scatters or passes through matter, it tends to interact with molecules and atoms. Since atoms and molecules have resonance frequencies, they directly interact with those light waves having the exact frequencies. When collisions occur in an excited state, the atoms and molecules emit light with a certain set of characteristic frequencies. This further results in a line spectrum. Here, only light with detached wavelengths is produced. The spectrum is also not continuous, but it consists of a set of emission lines.

Lepro products are very easy to install. Just follow the 3 easy steps as follow:1. Dry and clean the surface2. Unroll the strip light, cut the light strip if necessary3. Stick light strip to the surfacePlease visit detailed LED strip lights installation guide to watch video and get more details.

The color temperature of light is referred to as CCT (Correlated Color Temperature), and it is measured in degrees Kelvin (K). White light's appearance is directly influenced by the temperature rating, which ranges from cool white (6500K) to warm white (2700K). The color will transition from yellow to yellowish white to white and then a bluish white (the coolest) as the Kelvin temperature rises.

1. Make sure max wattage of power adapter is enough for strips you want to connect. You can find wattage information on instruction of power adapter and LED strips.2. Use Lepro connector to connect two strips easily.

The human eye's perception of brightness is measured in “Lumens”. The following variables affect LED strip lights' brightness: LED output, the quantity of LEDs per square foot, and LED strip light wattage. Different projects call for a specific level of brightness to achieve the desired appearance. Always go brighter than necessary and add a dimmer, is our advice.

Nonetheless, the main significance of the electromagnetic spectrum is that it can be used to classify electromagnetic waves and arrange them according to their different frequencies or wavelengths.

Light wave

Microwave: This type of radiation is found in microwaves and helps in cooking at home/office. It is also used by astronomers to determine and understand the structure of nearby galaxies and stars.

This falls within the given visible spectrum frequencies. Being a high frequency on the visible spectrum, close to the frequencies emitted by blue colour, one could assume that you measured a colour close to blue, though cyan and green cannot be out of  question as the given frequencies are a bit vague. It is closest to the green colour. Hence, we measured the green colour.

We advise measuring the necessary length before choosing a light strip in order to get the best decorative effect. Avoid having a length that is either too long to cut short and waste, or too short to achieve the desired effect. Lepro provides customers with a selection of light strip lengths.

The electromagnetic waves in these different bands have different characteristics depending upon how they are produced, how they interact with matter and their practical applications. Maxwell’s equations predicted the existence of an infinite number of frequencies of electromagnetic waves, all travelling with the speed of light. This is the first indication of the existence of the entire electromagnetic spectrum.

An electromagnetic spectrum is a collection of a range of waves in sequential order. Radio waves have the highest frequency, and gamma rays have the shortest wavelength.

We should use the equation involving energy change, Planck’s constant, and frequency. Next, we need to figure out what we are solving for. In this problem, they ask for the possible colour that you measured. If we relate the energy with Planck’s constant, we can solve for frequency. We are given the energy, 4.0 x 10-19 joules, as well as Planck’s constant, 6.6256 x 10-34 joules/sec. Also, we are given the frequencies emitted by the visible spectrum, from red to violet. This problem is easy to solve now. If we solve for the frequency, we can then relate it to the energy emitted, measured in either sec-1.

3) EM waves also exert pressure, which is shown by a radiometer. One side of the panels is black, the other side is white, and the panels spin due to the pressure differences under the light.
