Assertion : Contribution of the wavelets...

Assertion : Contribution of the wavelets lhying on back on a wavefront is zero.
Reason : The contribution of a wavelet in any direction making angle `theta` with the wavelet is proportional to `1/2( 1 + cos theta)`. In the case, `theta= 180^@`.

A

Assertion is True, Reason is True, Reason is a correct explanation for Assertion

B

Assertion is True, Reason is True, Reason is not a correct explanation for Assertion

C

Assertion is True, Reasonis False
