4. What is the related topics?Electromagnetism, Maxwell's equations, Radio waves, Wave physics, Experimental physics
5. What did Heinrich Hertz discover about radio waves?He proved that radio waves are real and act like light, showing they can reflect, focus, and bend.
6. How did Hertz show that radio waves exist?He built a spark‑gap transmitter that made sparks jump and a receiver that sparked when the waves arrived, proving the waves were real.

Electromagnetic Waves: Oscillating electric and magnetic fields that propagate through space, carrying energy and momentum.
Resonance: The phenomenon where a system vibrates with maximum amplitude when driven by an external force at its natural frequency.
Spark-Gap Transmitter: An early radio transmitter that generates high-frequency oscillations by creating electrical sparks across a gap.
Frequency: The rate at which a wave oscillates, measured in Hertz (Hz), representing cycles per second.
