	Actually, I'm sure physicists believe they understand electricity and 
magnetism to the letter. They consider the theory to be complete (and 
have for ages). So they'd probably disagree with you there.

	For a single photon, frequency is proportional to energy. A photon has 
both wave and particle properties, as does your finger, and just about 
anything else in the world. May be hard to fathom, but it's not unique 
to light.

	Just needs to oscillate at the frequency of light - I have no idea if 
it's practical, though.
