Question

The refractive index ju of a transparent medium varies
with wavelength of light as refractive index
= A +( B/wavelength square)
Where A and B are constants. Find the dimensional
formula and SI unit of and B.​

Answer 1

Answer:

A is dimensionless.

Dimension of B/ λ^2 =>

                     [B] / [L^2] = [M^0L^0T^0]

                                [B] = [M^0L^2T^0]

Or,                  [B] = [L^2]
