What is the primary cause of spherical aberration?
AnswerClick to flip back
A
Imperfect curvature of the lens surfaces
💡 Explanation:
Spherical aberration arises due to the variation in the angle of incidence of light rays striking the lens at different distances from the optical axis. This results in different focal points for rays passing through different parts of the lens, leading to a blurred image.
