Light emitting diodes (LED) maybe defined as a semiconductor device that generates light by using the solid sate electronics.
In 1921 Albert Einstein won the Nobel Prize for discovering the law which governs the photoelectric effect.
Maxwell’s most significant scientific achievement was his electromagnetic theory of light propagation which he first presented in 1864.
The development of fiber optic technology has driven the dramatic progression of telecommunications.
Wavenumber is defined as the number of complete wave cycles per unit length of a linear space. It can also be referred to as the spatial frequency of the waves represented in radians per unit distance, or cycles per unit distance.
The term photon was coined by Gilbert Lewis in 1926. A photon is a type of elementary particle that forms the basic unit of electromagnetic radiation, which includes infrared, ultraviolet, visible light, X-rays, radio waves, and gamma rays.
A prism is a transparent geometric optical object with a minimum of two polished plane faces inclined relative to each other, from which light is reflected or through which light is refracted.
A periscope can be defined as an optical instrument that allows the viewing of objects that are not in the direct life of vision. Periscopes prove to be of great help to submariners to have a view of the outside view.
Wei Min, Assistant Professor at Columbia University and his team have investigated the synthesis of protein at a specific site in the tissue of the brain using a new imaging technique in order to study the process of development of long-term memory.
