Reflection Class – XII

Newton’s equation:Let us consider an object AB is placed at a distance u from the pole of a concave mirror of focal length f. The image A/B/ is formed at a distance of v from the pole. Let us consider the distance between object and focus is FA = x = (u – f) and distance […]

Relation between object and image velocity: 1. When object is moving along the principal axis: Let us consider, a point object is moving along the principal axis of a concave mirror of focal length f. At any instant the object distance is u and image distance is v. Using mirror formula we get,   ——-
