Unwanted reflections limit the performance of light-based technologies, such as solar cells, camera lenses, and light-emitting diodes (LEDs). In solar cells, for example, reflections mean less light ...

Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

Fran: I am looking at my reflection. When light from an object is reflected by a surface, it changes direction - it bounces off the surface. So, if we shine this light onto this mirror, then we can ...

Mirrors such as those found in a bathroom tend to be made from a sheet of transparent glass or plastic and a layer of smooth, polished aluminium (or in older mirrors, silver). The reason why light ...

Through the looking glass: Scientists at the City University of New York (CUNY) created a "mirror" that can reflect an electromagnetic wave backward in time. It is not the first time this has been ...
