In this paper, we generalize this definition of caustics to the hyperbolic 2-space and to front mirrors that may have singularities, and we investigate caustics of light rays on the hyperbolic 2-space reflected by hyperbolic front mirrors. For this investigation, we first introduce hyperbolic ...

When light hits a flat mirror, it is reflected to our eyes. It is also reflected to the rest of our bodies. It does not bounce perfectly off of our heads, eyes or other body parts facing the mirror. The rays that are refracted from our bodies then hit the mirror at varying angles a...
the ratio between the light reflected from a surf ace and the total light falling upon that surf ace, as the albedo of the moon. birefringence double refraction; the separation of light into two unequally refracted, polarized rays, as by some crystals. — birefringent, adj. ...

Retroreflection is an optical phenomenon whereby light rays strike a specific surface, a retroreflector, and are redirected to the light source along the inverse direction of the incident light. From: Biosensors and Bioelectronics, 2022 About this pageSet alert ...
The moon also provides light, but it doesn't produce light of its own. The light which we get from the moon is the light that is being reflected by the moon from the Sun. Certain natural phenomenons also emit light, such as volcanic eruptions and lightning. There are some living organis...

Ancient Greeks argued over whether light rays emanated from a person's eye or the object being viewed. iStockphoto/Thinkstock Over the centuries, our view of light has changed dramatically. The first real theories about light came from the ancient Greeks. Many of these theories sought to ...
