Radio waves are electromagnetic radiation, which was first discovered by the German physicist Heinrich Hertz in 1887. Radio waves are crucial to radio communications and radio determination. In a vacuum, radio waves move at the speed of light. Radio waves travel close to this speed on Earth but are slowed down by the atmosphere. The electromagnetic spectrum is divided into seven different regions. The six other regions are visible light, microwave, infrared (IR), ultraviolet (UV), and gamma-rays. Each region has a different range of wavelengths, energies, and frequencies. Radio waves are the longest of all the regions of the electromagnetic…
