For good contrast between and minima in inteference pattern two sources of light should be

A

coherent

B

monochromatic

C

narrow

D

equally bright

Text Solution

Verified by Experts

The correct Answer is:
D
For equally bright sources, amplitudes of waves are equal, the dark fringe. i.e., minima is completely dark and so a good contrast between maxima and minima is obtained.
