The electromagnetic spectrum is divided into seven different frequency ranges which are from lowest to highest, radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
The electromagnetic spectrum includes electromagnetic waves with frequencies between one hertz and above 10²⁵ hertz, or wavelengths between thousands of kilometres and a small portion of the size of an atomic nucleus. The electromagnetic waves found within each of these bands are referred to by a different name. Starting at the low frequency(long wavelength), end of the spectrum, these are radio waves, micro waves, infrared, visible light, ultraviolet, x-rays and gamma rays. This frequency range is divided into separate bands.
