Calculate the length of a radio wave picked up by a car radio tuned to. The radio wavelength equals the velocity of the radio wave divided by the frequency. In this case, the frequency is 89.3 MHz (8.93 X 107 Hz) and the velocity is the speed of light (3.0 X 108 m/s, for all waves in the electromagnetic spectrum). The calculations are as follows:
