In Young's experiments the two sources are independent indentical bulbs of same power. What happees to the interference pattern ?

A

Intensity of bright fringes is doubled

B

Intensity of bright fringes becoms 4 times

C

Intensity is uniform and no fringes are oberved

D

Two sets o fringes overlaps giving darkness

Text Solution

Verified by Experts

The correct Answer is:
C
The superimposing waves will not be haivng a constant phase difference. This leads to general illumination and no fringes are observed.
