Question

What is refraction of light? Draw the diagram of refraction of light in glass slab. Write the laws of refraction.

Answer 1

Refraction of light:

1. Refraction is the bending of a wave when it enters a medium with a different speed.
2. It can be defined as a change in the direction of a wave as it passes from one medium to another or as a gradual change in the medium.

Laws of refraction:

1. At the point of incidence, the incident ray, refracted ray, and normal to the interface of two media all lie on the same plane.
2. The sine of the angle of incidence to sine of the angle of refraction ratio is constant. Snell's law of refraction is another name for this.
