Question

with the help of a diagram state the meaning of refraction of light State Law of refraction of light and also Express it mathematically​

Answer 1

Answer:

Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. ... Refraction is responsible for image formation by lenses and the eye.

The law of refraction, which is generally known as Snell's law governs the behave of light rays as they propagate across a sharp interface between two transparent dielectric media. ... the incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.

Answer 2

Step-by-step explanation:

law of refraction

1) the angle of incidence is equal to the angle of refraction

2)the incident ray , the normal ray and refracted ray , all lies in same plane

light travelling obliquely from one medium to another, the direction of propagation of light in the second medium changes. This phenomenon is known as refraction of light.
