![]() This is the key to providing an awesome and stimulating visual experience. Light waves ordinarily will not bend around corners, but they will be diffracted when they pass through tiny openings. Another more familiar form happens when a light hits the back of your favorite CD, casting a rainbow of colors, or simply the hologram on your credit card is the result of light grating. A couple everyday examples are water waves spreading out as they move around an obstacle such as a projecting rock in a stream. Throughout the years, their observations were studied and molded into the theories and laws, which govern, light diffraction as we know it today.ĭiffraction, in physics, is the spreading out of waves, such as those of water, sound, radio, or light, as they pass around an obstacle or go through an opening. Francesco is also known for coining the term “diffraction,” from the Latin “diffringere,” ‘to break into pieces.’ Fast forwarding through history, a scientist named James Gregory observed the first form of diffraction grating, by studying the light break up caused by bird feathers. This is the exact same visible spectrum that you see when wearing diffraction glasses today! During this time a man by the name of Francesco Maria Grimaldi, also observed and characterized what would soon be known as light diffraction. What he discovered is that light is made up of a spectrum ranging from 7 different visible colors. The history of diffraction goes back far beyond over 300 years ago, when Sir Issac Newton observed a beam of sunlight pass through a glass prism. Now imagine looking at hundreds of holiday lights, fireworks, or lasers, and you can see why diffraction glasses have really become so popular. Check out what diffraction glasses really look like when viewing a single light source!Īs you can see, just looking at a single light source creates a burst of colors. White light will show the widest array of colors, whereas looking at a blue light for example will show its component colors. This is the main principle behind what gives diffraction glasses their awesome visual sensation. But what is diffraction really? Diffraction is defined as the process by which a beam of light waves is spread out as a result of passing through a narrow aperture or across an edge or “grating”.As the light passes through this grating, eachīeam of light is split into its individual spectrum of colors turning white light into a full rainbow spectrum. With its exciting effects, it’s taking the nation by storm. You may have been recently introduced to a revolutionary visual experience called diffraction glasses. ![]() Enhancing any light-shows or performances.Visualizers on as iTunes windows media player. ![]()
