How will the diffraction pattern of single slit change when yellow light is replaced by blue light? The fringe will be

A

wider

B

narrower

C

brighter

D

fainter

Text Solution

Verified by Experts

The correct Answer is:
B
Frings width `prop` wavelength of light.
Since, wavelength of blue colour is less than yellow colour.
Therefore, fringe will become narrower.
