Define central ray in physics
Did you know?
A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector. Light rays in homogeneous media are straight. They bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes. … See more In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of See more • Collimated beam • Optical path • Optical path length • Paraxial approximation See more There are many special rays that are used in optical modelling to analyze an optical system. These are defined and described below, grouped by the type of system they are used to model. Interaction with surfaces • An … See more 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.
