Red light is generally used to observe diffraction pattern from single slit. If blue light is used instead of red light, then diffraction pattern

A

Will be more clear

B

Will contract

C

Will expanded

D

Will not be visualized

Text Solution

Verified by Experts

The correct Answer is:
B
`(lambda)_("blue") lt (lambda)_("Red")`
Hence, fringe pattern will contract because fringe width `prop lambda`
