Question

Quizplus · Accepted Answer

Chromatic aberration occurs because different colors of light are bent (refracted) by different amounts as they pass through a lens. This phenomenon is specific to refracting telescopes, which use lenses to gather and focus light. Reflecting telescopes, which use mirrors instead of lenses, do not suffer from chromatic aberration.
