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 electromagnetic spectrum. All the different kinds of electromagnetic radiation are essentially the same stuff as light: they're forms of energy that travel in straight lines, at the speed of light (300,000 km or 186,000 miles per second), when electrical and magnetic vibrations wiggle from side to side.
