If the amplitude of two interfering light waves are not equal, then the intensity in the dark region formed in the interference pattern will be

A

Zero

B

Same

C

Less

D

More

Text Solution

Verified by Experts

The correct Answer is:
D
For complete darkness, the amplitudes of the two waves must be equal so that `A_(1)-A_(2)=0`. But if `A_(1) ne A_(2)`, the resultant amplitude and hence the intensity will not be zero.
