Hertz also identified the photoelectric effect, the method by which specific metals get an electrical likely when subjected to light. He could not explain this behavior, and, in truth, there was nothing at all in wave principle that would account for it.
Deceleration of a free of charge charged particle, like an electron, can develop obvious radiation: cyclotron radiation, synchrotron radiation and bremsstrahlung radiation are all examples of this. Particles shifting through a medium more rapidly than the speed of light in that medium can produce seen Cherenkov radiation.
