Refractive Index

occurs due to...

Question

_______ occurs due to change in the speed of light when it enters an optical medium of different optical density.

Open in App

Solution

When light travels from one medium to another medium with different refractive indices, then the speed of light and its wavelength change.
Basically, the speed of light depends upon the medium properties in which the light travels.
Hence, the Refraction of light occurs due to change in the speed of light when it enters an optical medium of a different optical density.
