In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow. [1][2] Rays are used to model the propagation of light through an optical system, by dividing the real light ...
Geometrical optics. Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays: may ...
Mar 26, 2024 · Ray optics, also known as geometrical optics, is a branch of physics that studies the propagation of light by treating it as a collection of rays. These rays are essentially imaginary lines that represent the direction in which light travels. The form of energy that helps us see the objects around us is called light.
Optics, in a simple manner, is used to describe the behaviour of visible light, infrared light, and ultraviolet. Imaging is done with the help of a system called an image forming an optical system. Ray optics is also called geometrical optics. It is a branch of science that describes light propagation in terms of “rays”.

- Optics is the study of the wave properties of light, which can be grouped into 3 categories: Interference Diffraction Polarization
- According to the source of light, wavefronts can be of 3 types: Spherical wavefront Cylindrical wavefront Plane wavefront
Based on the specific method of approximation, optics has been broadly divided into two categories, namely: i. Geometrical Optics (ray optics), treated in the first half of the class. Emphasizes on finding the light path. Especially useful for studying the optical behavior of the system which has length scale much larger than the wavelength of ...
Jul 7, 2023 · Ray Optics is also called Geometrical Optics. Ray Optics is all about the geometry of falling light. Since light always travels in a straight line and the direction in which light is propagated from the source is termed as the ray of light. i.e., the imaginary straight line drawn from the source used to understand the direction of propagation is known as a ray of light.

The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror. 25.2: The Law of Reflection. The angle of reflection equals the angle of ...
