A) Red light has a longer wavelength and higher frequency than does blue light.
B) Red light has a longer wavelength and lower frequency than does blue light.
C) Red light has a shorter wavelength and higher frequency than does blue light.
D) Red light has a shorter wavelength and lower frequency than does blue light.

Question

Quizplus · Accepted Answer

Red light has a longer wavelength than blue light, meaning it has less frequency, since the frequency is inversely proportional to wavelength (i.e., longer wavelength means lower frequency, and shorter wavelength means higher frequency).
