Options

A. Refraction
B. Diffraction
C. Propagation
D. No option is correct

Answer

A

Explanation

The phenomenon of bending of light as it passes from one medium to another is known as the refraction of light. Refraction is the change in direction of a wave due to a change in its medium. It is essentially a surface phenomenon. This is most commonly observed when a wave passes from one medium to another at any angle other than `0^(@)` from the normal.
