My notes say that Heinrich Hertz was the first to generate and detect EM waves in the lab.
... Uhhh, this might seem really basic to you guys, but what exactly are EM waves?
Because I thought they were any type of wave that appears on the electromagnetic spectrum, including visible light. So how is it that this guy was the first one to generate them in a lab? I mean, don't you just turn on a light??
