If a torch is used in place of monochromatic light in Young's experiment what will happen?

A

fringe will appear for a moment and then it will disppear

B

fringe will occure as from monochromatic source

C

only bright fringes will appear

D

no fringe will appear

Text Solution

Verified by Experts

The correct Answer is:
D
When the torch is used in the Young's experiment, the fringe will overlap, due to the different colours in a very confusing ways. So, it will not give a clear interference pattern. Hence, no fringe will appear/
