WebCDs are read by interpreting variations in reflections of a laser beam from the surface. Some barcode scanners use a laser beam. Lasers are used in industry to cut steel and other metals. Lasers are bounced off reflectors that astronauts left on the Moon. WebHow is the refractive index of any medium ' A A A A ' with respect to a medium ' B B B B ' related to the speed of propagation of light in two media A A A A and B B B B? State the name of this constant when one medium is vacuum or air. The refractive indices of glass and water with respect to vacuum are 3 / 2 3/2 3 / 2 3, slash, 2 and 4 / 3 4/3 ...

WebPart 2: Diffraction from a CD Finally, you will measure the width of tracks on a CD by reflecting laser light off of it and measuring the resulting diffraction pattern. Part 3: Thickness of Human Hair Next you will discover the ability to measure the size of small objects using diffraction, by measuring the width of a human hair. WebWhen light refracts, it follows the law of refraction n i sin (c i )=n r sin (c r) where n is the index of refraction. The number in the left-bottom corner i is the angle of incidence, r is the angle of refraction. Most of the light is refracted out by ray 2. WebNow, we know from refraction indices, or just in general, that light moves slower in water than it does in air. So it's slower in water and faster in air. So let's think about what's going to happen. Let me draw two rays that are coming from this point on the straw right over here. shoot loops gangster cereal
