Diagram illustrating the electromagnetic spectrum. The changing wavelength of electromagnetic (EM) radiation through the spectrum is shown by the trace along bottom. The corresponding frequencies in meters are shown along top. At the low wavelength end (right) of the EM spectrum are radio waves, microwaves and infrared radiation. At the high wavelength end (left) of the spectrum are gamma rays, X-rays and ultraviolet light. Visible light, at centre right, is a mid-frequency range of wavelengths that can be seen by the human eye.
