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 depends on the wavelength.

Question

Quizplus · Accepted Answer

Spherical aberration occurs because the outer edges of a lens have a different radius of curvature than the central region, causing the rays of light passing through the edge and center to converge at different focal points.
