What is the path difference of destructive interference

A

`nlambda`

B

`n(lambda+1)`

C

`((n+1)lambda)/(2)`

D

`((2n+1)lambda)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
For destructive interference Path difference ( `Deltax`) = odd multiple of `lambda//2= (2n+1) lambda//2`
