What causes chromatic aberration?
A) the index of refraction is a function of wavelength
B) the outer edges of the lens produce a focus at a different point from the central rays
C) the absorption of light in the glass is a function of wavelength
D) the coefficient of reflection is a function of wavelength

Question

Quizplus · Accepted Answer

Chromatic aberration is caused by the index of refraction being different for different wavelengths of light. This causes different colors of light to be refracted at slightly different angles, leading to a blurring or separation of colors in the image.
