               LESSON NOTES:


               Image formation by convex mirrors
                     In order to construct a ray diagram to find out the position, nature and size of
                       image formed by convex mirror we should remember following path of rays of
                       light.
                     A ray of light parallel to the principle axis of a convex mirror appears to be
                       coming from its focus after reflection from the mirror.
                     A ray of light going towards the center of curvature of convex mirror is
                       reflected back along its own path.
                     Convex mirrors have its focus and center of curvature behind it and no light
                       can go behind the convex mirror and all the rays that we show behind the
                       convex mirror are virtual and no ray actually passes through the focus and
                       center of curvature of the convex mirror.
                     Whatever be the position of object in front of convex mirror, the image formed
                       by a convex mirror is always behind the mirror, virtual, erect and smaller than
                       the object.
                     Nature, position and relative size of the image formed by a convex mirror is
                       given below in the
























                     Convex mirrors are used as rear view mirrors in automobiles to see the traffic
                       at back side as they give erect images and also highly diminished one giving
                       the wide field view of traffic behind.
