Dispersion is
A) the dependence of a wave's amplitude on the time it has been traveling.
B) the dependence of a wave's frequency on its amplitude.
C) The dependence of a wave's speed on its wavelength.
D) The dependence of a wave's speed on its amplitude.

Question

Quizplus · Accepted Answer

Dispersion refers to the phenomenon where the speed of a wave depends on its wavelength. Different wavelengths travel at different speeds, leading to the spreading out of the wave over time, especially in a medium where the wave speed varies with wavelength.
