What causes the refraction of light?

The cause of the refraction of light is that light travels at different speeds in different media. This change in the speed of light when it moves from one medium to another causes it to bend.

Refraction is caused due to the change in speed of light when it enters from one medium to another.

  1. When the light goes from air into water, it bends towards the normal because there is a reduction in its speed.
  2. When the light goes from water to air, it bends away from the normal because three increases the speed of light.

What is refraction?

Refraction is the change in the direction of a wave passing from one medium to another.

Laws of refraction state that:

  • The incident ray refracted ray and the normal to the interface of two media at the point of incidence all lie on the same plane.
  • The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.
