- About the spark in Hertz creation and detection of EM waves
Hello, so I was reading bout the Hertz experiment in different text and they always say something about the Spark causing accelerated electric charge. So I was wondering, is the spark necessarily for the production of EM waves? If yes, why? Because as I recall, applying an ac voltage should create oscillating charge in the two electrodes which should create em waves with or without a spark. Please, tell me how I'm wrong.
Thanks in advance.
