The frequency value in the electromagnetic spectrum ranges from below one Hz to above 10 19 hertz, and the wavelengths can vary from around the size of an atomic nucleus to thousands of kilometers.

But electromagnetic waves also exist on either side of the visible spectrum. On one side is low-frequency, long-wavelength radiation.

The human eye can perceive only a small range of wavelengths of radiation. Ali Damouh/Science Photo Library via Getty Images Color perception depends on the surrounding environment. Michael J. Murdoch ...
