J.C. Bose discovered the ultra-short radio waves
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. Transmitters and receivers are typically designed to operate over a limited range of frequencies.
- Radio waves can travel for a long distance.
- Radio waves can penetrate through materials.
- Radio waves cannot be felt, and they are invisible.
