plz explain snells law ​

Answer 1

Raio of Sine of angle of Incident to the sine of angle of Refraction is constant or the pair of media in contact. This constant is written as 'n2. It represents the Refractive Index of medium (2) with respect to medium (1). This is also called Snell's Law.

                      Sin i                         n2

                      —––     =  'n2   =     —

                      Sin r                        n1

Hope this helps :)
