Starting from the smallest wavelengths (highest frequencies) and leading up to the biggest wavelengths, I am going to discuss each type of electromagnetic radiation, giving sources, means of detection and uses.

All these waves travel at the speed of light, that is, 299792459.0ms-1 (± 8). The speed of light is called c for ease of use. The wavelength and frequency of a wave are linked by the equation

The shorter the wavelength the greater the penetration.

See ' for more details on the different types of waves.
