Two coherent point sources S(1) and S(2)...


Two coherent point sources `S_(1)` and `S_(2)` are separated by a small distance 'd' as shown. The fringes obtained on the screen will be:

A

concentric circle

B

points

C

straight lines

D

semicircles

Text Solution

Verified by Experts

The correct Answer is:
A

As shown in figure, fringes meet in a concentric circle on screen. Also there are two cones whose vertices are `S_(1) and S_(2)` obtained on the screen with spiralised bases.
