Expert Answer
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.
