B

Statement-1 is true Statemetnt-2 is True,Statement -2 is NOT a correct explanation for statement -1.

C

Statement -1 is true,statement -2 is false

D

Statement -1 is False ,statement -2 is True.

Text Solution

Verified by Experts

The correct Answer is:
B
Wavelength in a medium of refractive index `mu`.
`lambda'=(lambda)/(mu)` where `lambda `is wavelength in air.
fringe width `omega=(lambdaD)/(d)`
