Light Rays
... Light from the sky is gradually refracted more towards the horizontal as the air near the ground has a lower refractive index (optically less dense). Total internal reflection takes place when it meets a layer of air at an angle greater than the critical angle. The image of the sky is then formed on ...

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.
