In Young's double slit experiment, the distance between two slits is made three times then the fringe width will becomes

A

9 times

B

1/9 times

C

3 times

D

1/3 times

Text Solution

Verified by Experts

The correct Answer is:
D
`w = (lambda D)/(d)`
`w. = (lambda D)/(3d)`
`:. (w.)/(w) = (1)/(3)`
`w. = (1)/(3) w`
