WebThe task of determining the direction in which an incident light ray would reflect involves determining the normal to the surface at the point of incidence. For a concave mirror, the normal at the point of incidence on the mirror surface is a line that extends through the center of curvature. WebAnswer (1 of 3): As the name suggests , paraxial rays , this word is made from two words parallel and axis , so the rays which are parallel to the principal axis basically of mirror or lens are known as paraxial rays. They are those rays which are close to the axis of aperture. They makes a sma...
