Two mirrors

What can you do here
Stand between the mirrors. See the image that multiple reflections of light create. By trial and error try to find the spot where you experience the strongest effect. Examine the phenomenon when there are two people between the mirrors.

How does it work
When looking at the mirrors we use the fact that smooth surfaces reflect lightwaves. Two parallel mirrors reflect light from each other, creating a seemingly never-ending series of reflections.

Interesting facts
Parallel mirrors are at times used in interior design to give the illusion the room is lengthened.
