What happens to the interference pattern...

What happens to the interference pattern if the two slits in Young's experiment are illuminated by two independent sources such as two sodium lamps S and S' as shown in figure

A

Two sets of inteference fringes overlaps.

B

No fringes are observed.

C

The intensity of the bright fringes is doubled.

D

The intensity of the bright fringe become four times.

Text Solution

Verified by Experts

The correct Answer is:
b
No fringes are observed as two independent sources are not coherent
