Radio waves vs light waves

Light is made of of particules which move in an approximate
straight line. I say approximate, because it's not going perfectly
straight. [snip] Radio waves is electricity. [snip] [etc]


No. Sorry, that's not how it works. There are previous answers in this
thread, I won't recapitulate, but radio is just "long light waves" and light is
just "very short radio waves". The wavelength makes all the difference.

that, except there's no cat.")
