Question

Tell about refraction laws.

Answer 1

Laws of Refraction

(1) The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane.

(2) For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

i.e. sin i/ sin r = RI ( of second medium with respect to first)

Answer 2

Laws of refraction - . 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.

2. For the light of a given color and for given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.
