The speed of radio waves
WebApr 9, 2024 · According to Maxwell’s theory, EM waves move at the speed of light, c = 3 x 108 m/s, and is created by oscillating electric and magnetic fields moving perpendicular to each other, in which a changing electric field yields changing magnetic field and vice versa. The first person to succeed was Heinrich Rudolf Hertz. WebAug 31, 2024 · The range of the radio spectrum is considered to be 3 kilohertz up to 300 gigahertz. A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space.
