A spherical mirror suffers from spherical aberration because
A) different colors are focused at different distances from the mirror.
B) a mirror of this shape is structurally weak and will sag under its own weight, distorting the image.
C) the starlight is distorted by turbulence in Earth's atmosphere.
D) different parts of the mirror focus the light at different distances from the mirror.

Question

Quizplus · Accepted Answer

Spherical aberration occurs because rays of light parallel to the principal axis but at different distances from it do not converge at the same point after reflection. This is due to the geometric shape of the spherical mirror, where rays farther from the principal axis are focused at points closer to the mirror compared to rays near the axis.
