Question

Define refraction.write the laws of refraction

Answer 1

Answer:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

Laws of Refraction are Laws of refraction state that: ... The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.
