How to make a "photo-multigraph" image showing the same person from five different angles, and the physics principles that make it all work.

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.

But you can’t actually create an infinite number of reflections, because in practice, mirrors aren’t perfectly reflective. Whenever a photon hits the reflective surface of a mirror, there’s ...

Students use mirror equations to determine the position and type.

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.

The explanation behind the reflection-based confusion is a relatively straightforward one and a case of simple physics. When it comes to reflections, the ray of light that approaches the mirror is ...

If you shine a light at a mirror, the beam is reflected inward to a central focal point, bouncing back toward you in a predictable manner—it’s a simple reflection of light, a spatial inversion.

From a flat mirror, designer light: Bizarre optical phenomenon defies laws of reflection and refraction Date: September 1, 2011 Source: Harvard University Summary: Exploiting a novel technique ...

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.
