Re: Hertz's Experiments
I'm a physicist, not a historian, but I can answer some of this.
Hertz used VHF or UHF, so wavelengths of a metre or so. These would diffract around corners well: they require fairly large objects to cast shadows. I've not heard of him using single slit diffraction. The Hertz wiki page
http://en.wikipedia.org/wiki/Heinrich_Hertz
has a nice diagram of his spark gap circuit.
Regarding Maxwell and Hertzian waves, Physclips shows simple but modern measurements of speed of light and speed of UHF radio at
