Infinite mirrors are a fun party trick, but the physics behind this phenomenon explains why it may not be true.

A mirror image is the result of light rays bounding off a reflective surface. Reflection and refraction are the two main aspects of geometric optics.

Both of these light rays travel towards the mirror and glance off of it—in such a way that the angle of reflection is equal to the angle of incidence. Got it?

Light travels from A, reflects off the bottom surface and then travels to point B. Show that for the path of least time, the angle of incidence is equal to the angle of reflection.

People Are Still Very Confused About How Mirrors Work People are asking how the mirror "knows" the object behind the paper is there.

Despite approaching the minimum thickness an object could possibly have and remain reflective under the laws of physics, the tiny mirrors reflected a great deal of the light shone on them.

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is … ...
