Optical path and geometrical path
WebSolution Suppose light travels a distance 'd' in time interval 'T' then the distance traveled by light in a vacuum in the same time interval is known as optical path length. In other words, the Optical path of a medium is defined as the distance d light travels in a vacuum at the same time it travels a distance d in the medium. WebGeometrical optics is commonly associated with the ray-like properties of light, such as, law of re°ection, Snell’s law, ray tracing, the optical path length and phase. The geometrical optics law of intensity and the optical wavefront are also well known, but are perhaps less used as a basis for optical design than ray tracing. This
