How is radio wave used
Web17 sep. 2024 · In early radiotelegraph systems, an operator used a key to generate pulses of radio waves. A “spark-gap” transmitter consists of two circuits separated by a spark gap – on the generating side, a capacitor is charged until there is enough energy to “spark” across the gap to the other side. Once there, the energy oscillates between a ... WebSuppose an RLC circuit in resonance is used to produce a radio wave of wavelength \( 139 \mathrm{~m} \).
