(D) When light passes through a lens,the refractive index of the lens material depends on the wavelength of the light. Since different colours have different wavelengths,they are refracted by different amounts. Consequently,rays of different colours do not focus at the same point after passing through a lens. This phenomenon is known as chromatic aberration.

The rays of different colours fail to converge at a point after passing through a thick converging lens. This defect is called
