If a convex lens of large aperture fails to converge the light rays incident on it to a single point, it is said to suffer from:
Correct answer: B. Spherical aberration
- A. (a) Chromatic aberration:
- B. Spherical aberration
- C. Both spherical and chromatic:
- D. Distortion:
Explanation
Explanation: Spherical aberration occurs when parallel rays of light incident on a lens do not converge to a single point due to the curvature of the lens surface.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
