The different types of electromagnetic waves are radio waves, microwaves, infrared, visible light, ultraviolet, X-ray and gamma rays. Radio waves have the lowest frequency and longest wavelength, while gamma rays have the shortest wavelength and highest frequency.

Some differences in electromagnetic waves are that they have varying wavelengths, frequencies and electromagnetic radiation emission. For example, electromagnetic waves that have high frequencies, such as gamma rays, will emit higher amounts of electromagnetic radiation than waves that are at the other end of the spectrum like microwaves.
