Prism, Dispersion & Scattering

When a beam of white light is allowed to pass through convex lens parallel to principal axis, the different colours of light converge at different points on the principal axis after refraction. This is called:

Show answer and solution

Answer: (d)

$\mu$ depends on wavelength, so $f$ differs for each colour ( $f_v < f_r$ ).
Different colours meet the axis at different points: chromatic aberration.
So the answer is (d).
