Fresnel worked out a number of formulas to calculate the way light changes direction, or refracts, while passing through glass prisms. Working with some of the most advanced glassmakers of the day, he produced a combination of prism shapes that together made up a lens. The Fresnel lighthouse lens used a large lamp at the focal plane as its light source. It also contained a central panel of magnifying glasses surrounded above and below by concentric rings of prisms and mirrors, all angled to gather light, intensify it and project it outward.

State of the art, one of the seven wonders of the Ancient World, the great lighthouse of Alexandria, built around 280 B.C., towered some 450 feet above Egypt's greatest harbor. At that height, it was the second tallest structure in the world, after another of the seven — the Great Pyramid of Giza. The light within, also state of the art, was an open flame.

By taking the advice of your negative reviews, you can find many ways to improve the sales and service experience to improve customer retention and acquisition.

After thanking them for their feedback and apologizing (if necessary) for the experience they had at the dealership, you should use your response to provide a specific solution to the customer issue. If necessary, take the conversation offline to further resolve additional issues.

Even if your efforts are unsuccessful it’s still worth responding to negative reviews. Doing so makes it more likely for 45 percent of consumers to visit you.

One of the best ways to get more positive reviews for your business is by delivering a customer experience that is worthy of a great review. This can be anything from being courteous and friendly to being transparent when it comes to pricing and financing. Cox Automotive revealed that 61 percent of those who purchased or leased a vehicle said their most recent purchase experience was about the same or worse than the previous visit.

Reviews are one of the main keys to a positive online reputation, and you should have a process in place to acquire new reviews from every customer that comes through your doors.

As big as it seems, by lighthouse standards the Smithsonian glass beehive is just above average, measuring nearly six feet high and more than three feet wide. It was installed in the famous Bolivar Lighthouse overlooking Galveston, Texas, sometime around 1907. This lighthouse served as sentry, and for some as sanctuary, during the deadliest hurricane in American history. The lens is visible proof that unlike the sea, light can be mastered by human ingenuity.

To that end, we created this handy guide so that you know where to find your Edmunds car dealer reviews and how you can use them to your advantage.

With your Edmunds.com car dealer reviews and ratings, prospective customers will know whether or not your dealership is worth their time, and more importantly, money. This puts the pressure on you to not only gather a steady stream of customer reviews but to also make sure that their feedback is positive and full of praise.

From that time until the 18th century, the lights that warned ships that they were approaching land improved hardly at all. Some burned coal. Others stuck with wood. Oil lamps backed by mirrors eventually offered a bit more candlepower. Still, every coastline in the world remained littered with the ribs of broken ships whose captains didn't see the lighthouse until it was too late. Then, in 1822, a frail scientist with a passion for optics made a revolutionary breakthrough. His name was Augustin Jean Fresnel.

How does a Fresnellenswork

An example of his greatest creation, a large object that looks like a crystalline beehive, may be seen inside the Hall of American Maritime Enterprise at the National Museum of American History. It towers above the museum's displays of ship models and marine artifacts. This is the Fresnel lens, not one lens really, but numerous tiers of prisms. Lenses like this one turned simple flames into beams upon which sea captains could take their bearings, avoiding risk to their ships and to the lives of their passengers.

It’s enough to simply garner a plethora of reviews on your Edmunds dealership page. You’ll need to interact with the customers that decide to leave feedback on your page. Research shows that 63 percent of customers never get a response to their reviews, and taking the time to do so can put you ahead of competing dealerships.

Fortunately, there are multiple ways to get these valuable pieces of feedback. You can provide a physical handout before they drive off in their new car or set up an automation process that will ask for reviews via SMS messages or email. There’s also the option to have a review process in place through a tablet at the dealership, or you can simply ask them verbally to leave a review.

If possible, point specific parts about their experience such as the salesperson they worked with or the vehicle they bought from you. This level of detail tells the reviewer that you are actually paying attention to their feedback, and it could be another step in improving the relationship with a potentially recurring customer.

One of the site’s unique features is Edmunds TMV, or True Market Value, which shows consumers the price that other buyers paid for a car with a similar make, model, trim, and additional options. This helps the customer get a better idea of a price range when it comes to negotiation, but dealerships can also take advantage of the Edmunds TMV as well.

For thousands of years, lighthouses created their lights with open flames which, naturally, were ineffective during high winds or rain. Then, in the 1690s, the glass lantern room was invented and first installed in England's Eddystone Lighthouse. Candles placed in the lantern room's glass lantern burned more brightly and securely than the earlier open fires. Another improvement came when pieces of mirrors placed in huge, round, wooden bowls served as crude reflectors that helped to direct the light. But throughout the 18th century, as maritime traffic increased, shipwrecks multiplied. The search was under way for a stronger, more reliable light.

The “Customer Reviews” section of your Edmunds dealership page will show your overall star rating, the total number of submitted reviews, and a small breakdown that shows which of the reviews recommend your dealership. Edmunds says that your star rating is based on all reviews spanning the last two years. Specifically, the rating incorporates reviews from the first day of the current month all the way back to the exact date two years ago.

In addition to the star rating and text, each reviewer will also need to provide additional details for their review. For sales-based reviews, Edmunds will show if the author recommends the dealership and if they purchased a vehicle from the dealer. For service-based reviews, Edmunds will ask the reviewer even more questions for further context. These include:

These customers are your promoters so make sure you thank them for their praise and the time they spent writing the review.

Reviews submitted by customers aren’t immediately posted to your Edmunds dealership page. A team of moderators from Edmunds will read and evaluate the review first to ensure that it follows the site’s guidelines before it is officially published. That entire process takes about two business days.

There is some controversy over who first placed parabolic mirrors behind flames to boost candlepower. L. Reynaud, an 18th-century chronicler and public works official, credited Swiss scientist Aimé Argand with the first installation of an apparatus using reflectors, in 1783. Argand also invented, in the 1780s, a long-burning smokeless oil lamp that removed the necessity of stoking the flames all night. But the greatest innovation was to come from Augustin Fresnel.

The various reflector systems installed in lighthouses during the 40 years preceding the introduction of the Fresnel lens certainly had been improvements over the open fires or candles in lantern rooms. Still, they could trap only a small percentage of the light. All prior systems paled by comparison with the Fresnel lens.

Rave reviews are one of the best sources of marketing for any dealership. These genuine reactions from real-world customers are valuable social proof for anyone looking to learn more about your dealership and how the customer experience stands out from the competition.

As a child, he was a slow learner who showed little interest in language studies or in tests of memory. By the age of 8, he could barely read. Yet his boyhood friends, for whom he studiously determined how to increase the power of popguns and bows, called him "the genius." When applied to optics, his genius proved to be real and considerable. Where others had improved existing lighthouse technology, Fresnel leapt forward by studying the behavior of light itself. His studies both advanced the understanding of the nature of light and produced the most important breakthrough in lighthouse lights in 2,000 years.

Fresnel lenses soon shone along the ragged coastlines of Europe, but surprisingly, America was slower to see the light. As mariners came to depend on Europe's powerful new lights, they complained bitterly about the puny lamps lighting America's coasts. Despite the clear superiority of Fresnel lenses, the parsimonious bureaucrat in charge of federal lighthouses, Stephen Pleasanton, considered the cost prohibitive. Finally, the uproar became so great that in 1838 Congress launched an investigation. It was not until then that Congress coughed up the cash to import a few Fresnel lenses. The first were installed in 1841 inside the two towers at Navesink Lighthouse, overlooking the approach to New York Harbor.

Only after 1852, when the United States created a Lighthouse Board made up of eminent scientists and mariners, including Joseph Henry of the Smithsonian and Alexander Bache of the U.S. Coast Survey, did the great lenses really begin to light America's coastline. By the Civil War, nearly all lighthouses in the United States had Fresnel lenses. It was shortly after the Civil War, however, before a beehive of prisms first shone from the Bolivar Light watching over Galveston. A Fresnel lens, similar to the one on display at NMAH, was still in use there in September 1900, when waves from the Gulf of Mexico began pounding the coast.

With time, Galveston recovered. The Bolivar Light served the city until 1933, then was replaced by another light on the south side of Galveston. The museum's lens served through the Galveston hurricane of 1915, then retired with the lighthouse and was stored by the U.S. Department of the Interior until it was transferred to the Smithsonian in 1976. By then, Augustin Jean Fresnel, who lived only a short while after inventing his great device, had been dead for nearly a century and a half. Along with the lens, Fresnel left behind his theories of light, which form the basis of modern optics. Today, the principle behind the Fresnel lens is used in the headlights of cars and in the flashing lights on police and emergency vehicles. And in a few older lighthouses around the country, and the world, Fresnel's elegant beehives still shine.

Research shows that an online review convinced 94 percent of consumers to avoid a business, and any of the negative reviews on your dealership page is enough to deter people away. However, this doesn’t mean that you should ignore these reviews entirely. You should still put aside some time to respond to their complaints.

Late in the morning of September 7, the U.S. Weather Station in Galveston learned by telegraph that a hurricane had just ripped across Florida and was somewhere over the Gulf. The next day, a telegrapher wired Washington, D.C. that Galveston was going under. Thousands died. Among the survivors were 125 people who found safety in the lighthouse. Keeper H. C. Claiborne exhausted a month's supply of food feeding the crowd. When the tower swayed in the wind, disabling the machinery that rotated the lens, Claiborne turned the lens by hand crank and kept the Bolivar Light shining through that terrible night.

The first Fresnel lens, installed in the elegant Cardovan Tower lighthouse on France's Gironde River in 1822, was visible to the horizon, more than 20 miles away. Sailors had long romanticized lighthouses. Now scientists could rhapsodize, too. "Nothing can be more beautiful than an entire apparatus for a fixed light," one engineer said of Fresnel's device. "I know of no work of art more beautifully creditable to the boldness, ardor, intelligence, and zeal of the artist."

Cox Automotive revealed that the people visit an average of two dealers when it comes to buying a new or used vehicle.
