Which kind of curved mirror never suffers from spherical aberration?

Question

Quizplus · Accepted Answer

Spherical aberration is a type of aberration found in optical devices with spherical surfaces, like lenses and mirrors, including both convex and concave types. It occurs due to the spherical shape of the mirror or lens, causing light rays that strike the surface at different distances from the center to be focused at different points. The question's premise is incorrect because all spherical mirrors (convex and concave) can suffer from spherical aberration. The only type of mirror that does not suffer from spherical aberration is a parabolic mirror, which is not listed among the options.
