f propto (1/μ-1) and μ propto (1/λ)

Q. The chromatic aberration in lenses is due to

Dissimilarity of main axis of rays

Dissimilarity of radii of curvature

Variation of focal length of lenses with wavelength

None of these

$f \propto \frac{1}{μ - 1}$ and $μ \propto \frac{1}{λ}$

Q. The chromatic aberration in lenses is due to

Dissimilarity of main axis of rays

Dissimilarity of radii of curvature

Variation of focal length of lenses with wavelength

None of these

f∝μ−11​ and μ∝λ1​

$f \propto \frac{1}{μ - 1}$ and $μ \propto \frac{1}{λ}$
