Electromagnetic waves are transverse waves in electric and magnetic fields. Electromagnetic waves can have a variety of wavelengths and frequencies, forming a continuous spectrum.
The regions of the electromagnetic spectrum with some applications, from longest to shortest wavelength, are:
Gamma waves are produced by .
When light moves from one material into another, it can change direction due to the change in speed of the light; this is called and is used in lenses.
