Re: Double concave mirror toy



I never said it did.

But it sure LOOKS like it does. Unless the beam is horizontal to image
(already mentioned in an earlier post)

PERFECT demo of how geometric light ray paths are reversible. Doubles the
worth of the demo. Kept students asking really good questions all day. Most
could puzzle it out without too much help.

Again
Thanks to Tom

Scott, the IMAGE reflects the laser? How can that be?

Just did this! How cool. Took most everyone in the department by surprise.

Thanks

Try shining a laser pointer on the real image. Ask students why
something
you can't touch seems to reflect light.
