A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector. Light rays in homogeneous media are straight. They bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes. … See more 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 See more • Collimated beam • Optical path • Optical path length • Paraxial approximation See more There are many special rays that are used in optical modelling to analyze an optical system.

WebAedenvelvet. 7 months ago. The centre of the reflecting surface of a mirror is called the Pole(P). It lies ON the mirror. This is different from the Centre of curvature(R). Each spherical mirror forms a part of an imaginary circle. The centre of this circle is called Centre of curvature. It DOES NOT lie on the mirror. WebFeb 20, 2016 · The amount of electric charge flowing through an X-ray tube during an exposure is the sum of tube current (mA) and duration of the exposure time in seconds (s). This is expressed as mA s and in order to obtain a short exposure time (e.g. 0.03 s for a chest radiograph) the electric current (mA) needs to be suitably higher.
