WebOptics. Optics is the popular branch of physics which deals with the determination of behaviour and the properties of the light. It also considers the interactions with the matter and also with the instruments which we need to detect it. Thus, optics describes the behaviours of visible light, infrared light as well as the ultraviolet. WebFringe width is the distance between two successive bright fringes or two successive dark fringes. In the interference pattern, the fringe width is constant for all the fringes. ... definition.
