In this blog I will be introducing what is snells law.
So keep reading to know what is Snell laws.
Snell’s law
The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of given
colour and for the given pair of media.
(sin i)/(sin r)=a constant.
This constant value is called the refractive index of the second medium with respect to the first.
