Radio waves, microwaves, infrared waves, and visible light are all types of electromagnetic radiation. They differ in their wavelengths, with radio waves having the longest wavelength and visible light having the shortest. The wavelength of an electromagnetic wave is inversely proportional to its frequency. Therefore, radio waves also have the lowest frequency, while visible light has the highest frequency.
