The rays of different colours fail to converge at a point after going through a converging lens. This defect is called(a) spherical aberration(b) distortion(c) coma(d) chromatic aberration

Answer»

(d) chromatic aberration.

EXPLANATION: 

Since the refractive index of a medium is different for different colors. Hence the rays of different colors fail to converge at a point. Since this aberration is related to colored rays it is called a chromatic aberration because chrome is a Greek word for color.
