Question

state the refraction of light​

Answer 1

Answer:

Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.

Answer 2

Answer:

Refraction is the bending of light when it travels from one medium to another. The refraction of light occurs due to the fact that velocity of light is different for different medium. Now the bending is governed by the laws of refraction and for light normal to the surface there is no bending but there is change of velocity of light.
