Question

calculate the angle of refraction in a medium of
angle of incidence in air is 48 and index of
refraction of medium
is
1:58​

Answer 1

Snell's law states that ratio of sine of angle of incidence to sine of angle of refraction is a constant. This constant is called the refractive index of the medium. Hence:
