Huygen's Principle:

(i) Every point on a given wave front (called primary wave front) acts as a fresh source of new disturbance, called secondary wavelets which travel in all directions with the velocity of light in the medium.

(ii) The forward envelope of these secondary wavelets gives the new wave front at any instance.This is called secondary wave front.

Consider a plane wavefront AB incident on a surface PQ separating two media 1 and 2.
The medium 1 is a rarer medium of refractive index n1  in which light travels with a velocity C1  The medium 2 is a denser medium of refractive index n2  in which light travels with a velocity C2.
