Why do we see a rainbow of colors reflected off a CD or DVD?

A rainbow is an optical phenomenon that can occur under certain meteorological conditions. It is caused by reflection, refraction and dispersion of light in water droplets resulting in an effect similar to a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun. WebApr 5, 2024 · Rainbows occur due to the phenomena like diffraction and internal full reflections. Theoretically there are several rainbows possible, but we can only see one generally. If you are lucky, you can see two. When light falls on the spherical water droplet, it enters the droplet. As the speeds of different wavelengths of light are different in ... terms for times of dayWebMar 5, 2024 · The angles of incidence and refraction are related to the impact parameter as follows: sinθ = b, cosθ = √1 − b2, sinθ ′ = b / n, and. cosθ = √1 − b2 / n2. These, together with Equation 1.7.1, give us the deviation as a function of impact parameter. The deviation goes through a minimum – and r goes through a maximum. terms for selling a business

Web• Explain everyday optical phenomena [mirages and apparent sun near the horizon] in terms of rays. • Explain why white light separates into a rainbow of colors when it passes through a prism. • Given the focal length of a thin lens and the object distance; locate the image, identify it as real or virtual, and calculate its magnification. The Short Answer: A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. See more A rainbow requires water droplets to be floating in the air. That’s why we see them right after it rains. The Sun must be behind you and the clouds … See more A full rainbow is actually a complete circle, but from the ground we see only part of it. From an airplane, in the right conditions, one can see an entire circular rainbow. See more Sunlight is made up of many wavelengths—or colors—of light. Some of those wavelengths get bent more than others when the light … See more The sunlight shines on a water droplet. As the light passes into the droplet, the light bends, or refracts, a little, because light travels slower in water than in air (because water is denser). Then the light bounces off the back of the … See more

WebRequired Conditions for Rainbow: To see a rainbow, three conditions are to be met. The sun should be behind the viewer. There must be plenty of water droplets in front of the viewer in the sky. Sunlight should be able to reach the water droplets; there should be no obstruction between the sun and the water droplets in the sky.
