My project in physics has a historical connection Grimaldi’s observation of colored effects with widths of luminous patches produced by lights of different portions from a light spectrum, Newton noticed that the band of red light was the biggest while the blue and green were either small or medium. It could be recombined to form white light again.You may have been recently introduced to a revolutionary visual experience called diffraction glasses. With its exciting effects, it’s taking the nation by storm. 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”.Diffraction, 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. A couple everyday examples are water waves spreading out as they move around an obstacle such as a projecting rock in a stream. These waves have been diffracted. 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. Light waves ordinarily will not bend around corners, but they will be diffracted when they pass through tiny openings. This is the key to providing an awesome and stimulating visual experience. When light strikes a grating (in our glasses this is the lens) which is marked with thousands of parallel lines, the light waves are caused to spread in such a way that they produce a spectrum, or rainbow, as pictured above! Even tiny water droplets can act as a grating to create a 3D prism of light diffraction.
