Some helpful advice if you are thinking of going into physics.
Don't.
I was pointing out to Bob Myers that we cannot see electric current
even if it oscillates at a frequency in the "visible light" range. What
is so incorrect about that?
If an electric current oscillates at a frequency in the "visible light"
spectrum, then we can see photons emitted as a result of the
oscillating electric current but we can't see the electric current
itself. Am I right?
Well, about as right as saying that you never see a person, a tree, a
car, a star, etc. etc., you just see the photons emitted or reflected
by those things. In the extremely restricted sense which you
attribute to the word "see", you can hardly see anything at all.
