Question

When white light travels through glass the refractive index of glass is found to vary with wavelength (μ​) = A + B/λ2

Using dimension calculation find dimensions A and B.

Answer 1

Refractive index has no dimension.
Thus if A+ (B/lambda ²) = refractive index.
Thn, A had no dimension and B has dimension of [ L²].
Hope I helped you.

Answer 2

Refractive index has no dimension.

Thus if A+ ($B\lambda^2$) = refractive index.

Thn, A had no dimension and B has dimension of [ $L^2$].
