Did you know?
WebRay optics, also known as geometrical optics, is the study of simple properties of light and optical instruments by assuming that light travels in a straight line. Ray optics deals with the geometry of the light. Light always travels in a straight line and the direction in which the light rays propagate is called the ray of light. WebNov 8, 2024 · One approximation that geometric optics makes is that the waves (rays) travel in straight lines until they hit a surface. When the ray encounters a surface it can either …
