The electromagnetic spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – visible light that comes from a lamp in your house or radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.

The order of the electromagnetic spectrum from highest energy/shortest wavelength to lowest energy/longest wavelength is as follows: Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared light, Microwaves, and Radio waves.

So, among gamma rays, ultraviolet rays, microwaves, and radio waves, radio waves have the longest wavelength.
