WebHow Hertz produced radio pulses? Hertz's spark-gap transmitter. ... The sparks caused violent pulses of electric current within the copper wires leading out to the zinc spheres. As Maxwell had predicted, the oscillating electric charges produced electromagnetic waves – radio waves – which spread out at the speed of light through the air ... Web21 jun. 2024 · Answer: The wire had its own spark-gap. Hertz applied high voltage a.c. electricity across the central spark-gap of the transmitter, creating sparks. The sparks caused violent pulses of electric current within the copper wires leading out to the zinc spheres. ... Hertz had produced and detected radio waves. thepandahd
