Light is incident from above on a thin sheet of glass (with air on both sides), which statement below is true? A. The light reflected from the top surface undergoes a 180 ° phase change and the light reflected from bottom surface does not. B. The light reflected from the bottom surface undergoes a 180 ° phase change and the light reflected from the top surface does not. C. Both rays undergo a 180 ° phase change. D. Neither ray undergoes a 180 ° phase change.
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
