Two Quick Light Experiments
... Electromagnet waves have a number of directions associated with them. As shown in the above figure, the electric field points along one direction (y in this case); the magnetic field points in another direction (z in this case); and the wave moves in another direction (x in this case). The direction ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
