In young's experiement, a creast of one wave coincides with the through of the other wave at a point. The phase difference between the two waves is

A

zero

B

`4pi`

C

`6pi`

D

`7pi`

Text Solution

Verified by Experts

The correct Answer is:
D
Crest of one wave coincides with trough of other wave, so phase difference is odd multiple of `pi`.
`thereforephi=7pi`
