WebAs it is a type of light it moves at the speed of light. Speed, wavelength and frequency are closely related, as described in diagram 2: So this means that if the wave has a frequency of 100 Hz it will travel its wavelength 100 times in a second. So the speed of a wave is its frequency multiplied by its wavelength. iphone screen repair prescott azWebJan 4, 2024 · Answer.
