Question
What causes chromatic aberration?
✓

Answer

  1. Variation of focal length of lens with colour
Explanation:
Chromatic aberration occurs when a lens is either unable to bring all wavelengths of color to the same focal plane and/or wavelengths of color are focused at different positions in the focal plane.
