Formula of ray optics

WebSnell's law (also known as Snell–Descartes law and ibn-Sahl law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.In optics, the law is used in ray … WebRay Optics (or, Geometrical Optics) explains the propagation of light in terms of rays. It deals with the behaviour of light. Light is usually considered a ray that travels in a straight path. Ray Optics Optics is a branch of physics that explains the behaviour of visible light, ultraviolet, and infrared light.
