Two monochromatic coherent point sources

S_1

and

S_2

are separated by a distance

L

. Each source emits light of wavelength

\lambda

, where

L >> \lambda

. The line

S_1 S_2

when extended meets a screen perpendicular to it at a point

A.

View answer and explanation

Correct option: A

The interference fringes on the screen are circular in shape

Option A (The interference fringes on the screen are circular in shape) is correct because when the screen is perpendicular to the line joining the sources, the fringes formed are circular.
