Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances.

Geometrical Optics: Based on rectilinear propagation of light Valid only If λ Light < < Size of obstacle Deals with image formation reflection and refraction Notes: Geometrical optics can be treated as the limiting case of wave optics when size of obstacle is very much large as compared to wavelength of light under such conditions

Geometrical Optics. When an object is dropped in still water, the circular wave fronts that are produced move out from the contact point over the two‐dimensional surface. A light source emits light uniformly in all directions of the three‐dimensional world. The wave fronts are spherical, and the direction of motion of the wave is perpendicular to By far the most important formula in geometrical optics, however, relates the position of an object placed in front of a lens to the position of its image, formed by the lens.
Arrow represents the direction of propagation of light. Figure shows a ray which indicates light is moving from A to B. Geometrical optics is the treatment of the passage of light through lenses, prisms, etc. by representing the light as rays.

Physics Note Geometrical Optics.The physics is one of the oldest academic disciplines, perhaps the oldest through the inclusion of astronomy. In the last two millennia, physics was a part of natural philosophy, chemistry, certain branches of mathematics and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique in its own right research programs. Geometric Optics Light from this page or screen is formed into an image by the lens of your eye, much as the lens of the camera that made this photograph. Mirrors, like lenses, can also form images that in turn are captured by your eye. Light - Geometric Optics A.

by representing the light as rays. A light ray from a source goes in a straight line through the air, but when it encounters a lens, prism, or mirror it bends or changes direction.
