Question

Explain the refraction of light and laws of refraction.

Answer 1

Answer:

heya ..

here is ur answer..

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 ofrefraction is constant.

i hope its help u

Answer 2

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

refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material. It is defined as. where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

Total internal reflection when refraction reflection at critical angle and refraction takes place called TIR
