The Light Show of Illusions

[Maxmars]

I have often wondered if light were affected like sound by the wave form. Can you see the difference between a sine wave and a square wave light? How about a saw tooth wave?

I am going to have to look into how such waves could be generated.

That's an excellent question!  Please let us know of what you learn.  I would expect any difference to be too subtle for us to detect visually... but hey, you never know.
