Refractive index mu is given as `mu=A+B/lambda^2,` where A and B are constants and lambda is wavelength, then dimensions of B are same as that of

A

Wavelength

B

Area

C

Volume

D

Velocity

Text Solution

Verified by Experts

The correct Answer is:
b
The refractive index has no dimensions.
`therefore (B)/(lambda^(2))` has no dimensions.
i.e. B has the same dimensions as that of `lambda^(2)` or `("Length")^(2)` or (Area).
