6A10.45 - Mirrors - Parallel Mirrors and Infinite Images

Code Number:
Demo Title:
Mirrors - Parallel Mirrors and Infinite Images
Area of Study:
Infinity mirror (table top model), Plexiglas mirrors with stand (1 mirror with a hole in the center), animal objects.

The table top mirror is ready to go once it is plugged in and turned on.

Place the two Plexiglas mirrors in the stand.  Place an object between the two mirrors and look through the hole at the multiple images.  You may also look over the top edge of the closer mirror and see the images.
