Solution
The correct option is B
refraction
When light ray enters from one medium to another, it bends and the speed of light ray also changes. This phenomenon is called refraction. The bending of light is because of the Fermat's principle which states that the path taken by a ray between two given points is the path that can be traversed by light in the least time.
