• Geometric Optics: The study of reflection and refraction of rays of light without reference to the wave or physical nature of light. The elementary studies of light are essentially geometric, graphical methods being used for determining the positions of images formed by lenses, mirrors, etc. It is still a valuable tool in the more advanced studies of technical optics.
