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.

Wave optics, also referred to as physical optics, is the branch of optics that enables important phenomena such as interference, diffraction, and polarization to be understood.
Ultraviolet (UV) light is a portion of the electromagnetic spectrum between the visible rays and X-rays. It lies in the frequency range of 10 to 400 nm with photon energies from 3 to 124 eV.
An accidental discovery by Robert Wilson and Arno Penzias in 1964 changed the entire landscape of cosmology and established the concept of a big bang as a keystone in our understanding of how the universe came into existence.
Optical density is a term used in the field of optical spectroscopy for describing the propagation of a wave through a material.
A folded resonator is a type of resonator construction in which the interior optical path is bent with the help of mirrors.
Catoptrics has been introduced way back in time by the ancient Greeks. There were two main ancient Greek texts that mentioned catoptrics.Catoptric systems are those optical systems that employ only mirrors for image formation.
