What causes spherical aberration?
A) the lens surface is not perfectly smooth
B) the outer edges of the lens produce a focus at a different point than the central rays
C) light is an electromagnetic wave with intrinsic diffraction properties
D) the absorption of light in the glass is a function of wavelength

Question

Quizplus · Accepted Answer

Spherical aberration occurs when the outer edges of a lens produce a focus at a different point than the central rays. This is because the curvature of the lens is not consistent across its entire surface.
