Chromatic aberration occurs in a refracting telescope when
A) the different colors of light do not focus at the same point.
B) some wavelengths are scattered out of the telescope by imperfections in the glass in the lenses or are reflected back by the front surface of the lens.
C) the lenses bend under their own weight, distorting the final image.
D) light from some wavelengths is absorbed by the lenses, distorting the colors of objects.

Question

Quizplus · Accepted Answer

Chromatic aberration in a refracting telescope is caused by the fact that lenses refract different colors of light at slightly different angles, leading to those colors not focusing at the same point. This results in a blurred image with color fringes.
