Which aberration arises because spherical surfaces are not an ideal lens shape?
AField curvature
BBarrel distortion
CChromatic aberration
DSpherical aberration
Answer & Solution
Correct answer: D. Spherical aberration
Rays far from the axis focus at a slightly different place than rays near the axis, since a sphere is only the simplest surface to grind.
