What is the cause of refraction of light when it passes from one medium to another?
Advertisements
उत्तर
The refraction of light (or change in the direction of path of light in other medium) occurs because light travels with different speeds in different media. When a ray of light passes from one medium to another, its direction (except for ∠i = 0°) changes because of change in its speed.
