Chromatic aberration in a lens is caused by: Correct Answer Dispersion

CONCEPT:

Chromatic aberration:

  • Chromatic aberration is a phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength.
  • Chromatic aberration occurs due to dispersion.
  • When it occurs a lens fails to focus all colours on the same point.

EXPLANATION:

  • Chromatic aberration is a phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength.
  • Chromatic aberration occurs due to dispersion. Hence, option 4 is correct.
