In double slits experiment, for light of which colour the fringe width will be minimum

A

violet

B

red

C

green

D

yellow

Text Solution

Verified by Experts

The correct Answer is:
A
Fringe width in double slit experiment is given by
`beta=(Dlambda)/d`
It implies that `betaproplambda` , so in given options `lambda_(v)` = minimum
