Yellow light emitted by sodium lamp in Y...

Yellow light emitted by sodium lamp in Young's double slit experiment is replaced by monochromatic blue light of the same intensity:

A

fringe width will decrease.

B

fringe width will increase.

C

fringe width will remain unchanged.

D

fringes will become less intense.

Text Solution

Verified by Experts

The correct Answer is:
A
we know that `beta=(lambdaD)/(d) & lambda_(yellow) gt lambda_(blue)`.
`rArr as `lambda` decreases, so `beta` also decreases.
