Question

explain secondary wave front​

Answer 1

Answer:

These wavelets travel with the velocity of light in the medium. ... To answer your question: A secondary wavelet means an imaginary point source at every point of the original wavefront emitting a spherical wave of the same form (or shape in time) as the original wave.

Answer 2

Explanation:

Explanation:If the source is very far (i.e. at infinite distance) the wave front is plane. If the source is in form of a slit at a finite distance, the wave front is cylindrical. (ii) Every point of the medium on a given wave front is a centre of originating new disturbance. This new disturbance is called the secondary wavelet.
