Question

state two laws of refraction of light
​

Answer 1

the first law of refraction of light white light is incident ray, refracted ray and normal all lie on the same plane.
the second law of refraction of light is the Sine of angle of incidence is equal to sine of angle of refraction

Answer 2

Hii!!!

LAWS OF REFRACTION OF LIGHT

1. The incident ray, the refracted ray and the normal at the interface of two transparent medium at the point of incidence all lie in a same plane.
2. The ratio of sine of angle of incidence to the sine of angle of refraction is a constant at a given color of light and for the given pair of media. This law is also called Snell's Law of Refraction.

$sini/sinr = Constant$

ALL THE BEST...☺☺
