Laws of Refraction of Light …
Laws of Refraction of Light is:
(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.
(2) The ratio sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media. This law is also known as Snell’ Law of Refraction. If i is the angle of incidence and r is the angle of refraction, then,
