Radio waves, microwaves, and infra-red waves have a short wavelength. The electromagnetic spectrum is a range of electromagnetic radiation that includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. The wavelength of electromagnetic radiation is inversely proportional to its frequency, so waves with a higher frequency have a shorter wavelength. Radio waves, microwaves, and infrared radiation have lower frequencies than visible light, so they have longer wavelengths. However, compared to other types of electromagnetic radiation, they have shorter wavelengths.
