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:
Transverse waves. All types of electromagnetic radiation, including visible light, are transverse waves waves. In transverse waves the vibrations are at right angles to the direction of travel, as seen in the animation below of a wave sent down a piece of string.
