Write about different points related to mirrors. |
|
Answer» The different points related to mirrors are 1) Vertex (P) : The point where the central axis touches the mirror is called vertex. 2) Focus or focal point (F): The light rays coming from distinct object appear to meet at point in case of concave mirror and tend to meet at point when drawn backward in case of convex mirror. That point is known as focus or focal point. 3) Centre of curvature (C) : It is centre of the sphere to which the mirror belongs. |
