Question

State Snells law of refraction

Answer 1

Answer..


The ratio sin of angle of incidence and angle of reflection is always equal.

Sin. I
Sin r. =. constant.

Answer 2

Answer:

snell' law of refraction is:- "the ratio of sine of angle of incident to sine of angle of refraction is always constant for given medium"

where,

 = refractive index of medium 2 with respect to the medium 1.

The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence , all lie in the same plane.
