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

Question

Quizplus · Accepted Answer

Chromatic aberration is caused by the fact that the index of refraction of a material, such as glass, varies with the wavelength of light. As a result, different colors of light passing through the same lens will be refracted by different amounts, causing them to focus at different points. This results in blurred or distorted images with fringes of color around the edges of objects, which is known as chromatic aberration.
