Put up a horizontal copper wire for an antenna with insulators on each end. hook the antenna to a tuner for light frequencies then to an amplifier then an oscilloscope. Sit back and watch your favorite light sine wave. Tune to different frequencies to see different wave lengths of light.
Does the antenna need to be grounded?

If it can pick up a radio wave, it can pick up a light wave. There's no difference except for the frequency. You would, of course, have to run it through a filter to get rid of unwanted frequencies. You'd also have to find a scope with a ridiculously high sampling rate. As for the grounding? Yeah, I suppose you could do that for safety, but it wouldn't be required to do what you're trying to do.

Sorry. It won't work. The wavelengths of light are much too short to induce volteges in the antenna since they are on the scale of atomic distances.
