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
Answer: (B) Chromatic aberration
The refractive index, and hence the focal length, depends on wavelength, so different colours focus at different points. This defect is chromatic aberration.
