Monochromatic Aberration

Can mirrors give rise to chromatic aberration ?

A : A reflecting type of telescope is preferred over refracting type in astronomy. R : A reflecting type of telescope is free from chromatic aberration and spherical aberration.

A laser light is focussed by a converging lens. Will there be a significant chromatic aberration ?

What condition must be satisfied by two thin lenses kept in contact so that they form an achromatic doublet, i.e., a combination free from chromatic aberration ?

A convex lens has mean focal length of 20 cm. The dispersive power of the material of the lens is 0.02. The longitudinal chromatic aberration for an object at infinity is

STATEMENT -1 : A convex lens suffers from chromatic aberration. and STATEMENT - 2 : All parallel rays passing through a convex lens do not come to a focus at the same point.

What is chromatic aberration? How can it be minimized or eliminated ?

What is the main reason for axial charomatic aberration in the formation of image by an lens ?

Assertion : A thick lens shows more chromatic aberration. Reason : Thick lens behave as many thin lenses.
