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:
The figure above shows all of the forms of electromagnetic radiation in order of INcreasing wavelength (given in nanometers (nm)) and DEcreasing energy. Notice how tiny the visible band is! There are some general properties shared by all forms of electromagnetic radiation: 1  It can travel through empty space. Other types of waves need some sort of medium to move through: water waves need liquid water and sound waves need some gas, liquid, or solid material to be heard. 2  The speed of light is constant in space.
