Speed of radio wave
WebAs Maxwell had predicted, the oscillating electric charges produced electromagnetic waves – radio waves – which spread out at the speed of light through the air around the wire. Hertz detected the waves with his … WebIts respective frequency range is what determines a wave’s type. Radio waves are a type of electromagnetic radiation with frequencies ranging from 300 GHz to as low as 3 Hz, and wavelengths ranging from 1 millimeter (0.039 inches) to 100 kilometers (62 miles). Similar to all other electromagnetic waves, they travel at the speed of light.
