Photographic film is a sheet of plastic coated with an emulsion containing light-sensitive silver halide salts that when exposed to light it forms a visible image. Through film developing, a chemical process applied to the film, a visible image is created. To create black and white photos there is only one layer of silver salts on the film and when exposed to light the silver salts block light and appear as the black part of the film. Color film uses three layers of salts and dyes in...

UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
