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. The electromagnetic spectrum consists of the full range of known electromagnetic waves, including gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.All of these are produced by various forms of oscillating charges or currents.amma Rays Gamma rays are the most energetic known form of electromagnetic radiation, with frequencies of 3*10 19 Hz (30 EHz) or higher and wavelengths of 10 -11 m (10 pm) or lower. They are produced from the decay of excited nuclei of radioactive elements.
