CBSE Class 12-science Answered

A point luminous source P is placed on the principle axis of a concave mirror of radius of radius of curvature 1m at a distance of 75 cm from its pole. At what distance from the concave mirror should a plane mirror be set so that the rays from P, after reflection from the concave mirror and then from the plane mirror again converge at the point P? Does the point of convergence of the rays change if they are first reflected at the plane mirror and then at the concave mirror?
