From what you know about the refraction of various wavelengths of visible light, would red light and blue light from the same source produce images at the same place?
A) Yes.
B) No. Red light would make an image closer to the lens.
C) No. Blue light would make an image closer to the lens.

Question

Quizplus · Accepted Answer

Blue light has a shorter wavelength than red light, which causes it to refract more when passing through a lens. As a result, blue light focuses closer to the lens than red light, leading to different image positions for each color.
