In young's double slit experiment, the path difference between two interfering waves at a point on the screen is `frac{5lambda}{2}` , `lambda` being wavelength of the light used. The ----------- dark fringe will lie at this point.

A

`pi`

B

`(3pi)/2`

C

`5pi`

D

`3pi`

Text Solution

Verified by Experts

The correct Answer is:
B
We know that, phase difference in YDSE experiment `phi=(npi)/2`
Here, `n=3 rArr phi=(3pi)/2`
