Vedclass · Answer

(B) The phenomenon where a lens fails to focus all colors to a single point is known as chromatic aberration. This occurs because the refractive index of the lens material varies with the wavelength of light (dispersion). Since the focal length $f$ of a lens depends on the refractive index $n$ according to the lens maker's formula, different colors (having different wavelengths) are refracted by different amounts, causing them to converge at different points along the principal axis.

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