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:
Electromagnetic waves are waves of energy formed by accelerating charge. They are classified by the wavelength, frequency, and energy. The electromagnetic spectrum is an illustration of such classification. At one end of the spectrum are the longer wavelength, lower frequency, and lower energy waves. At the other end are the shorter wavelength, higher frequency, and higher energy waves. The spectrum in order from the lower frequency to the higher frequency is radio waves, microwaves, infrared, visible light, ultraviolet, x-ray, and gamma ray.
