An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become

A

Wider

B

Narrower

C

Fainter

D

Brighter

Text Solution

Verified by Experts

The correct Answer is:
B
As `beta prop lambda`
`(lambda)_("Red") gt (lambda)_("Blue") implies (beta)_("Red") gt (beta)_("Blue")`
