Question

State snell’s law of refraction.

Answer 1

THE SNELLS LAW OF REFRACTION IS

SIN I/SIN R = N

Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of phase velocities in the two media, or equivalent to the reciprocal of the ratio of the indices of refraction:

sin I ∝ sin R

therefore

sin I = sin R ×k

where k is constant

so

sin I / sin R = k

Answer 2

Snell's law is a relationship between the angles of incidence and refraction which is equal to refractive index

n=sini/sinr
