Suppose refractive index

\mu

is given as

\mu=A+\frac{B}{\lambda^2}

where

A

and

B

are constants and

\lambda

is wavelength, then dimensions of

B

are same as that of

View answer and explanation

Correct option: D

Area

Option D (Area) is correct because for the equation to be dimensionally consistent, B must have the dimensions of wavelength squared, which is area.
