A point source is at a distance 35cm on the optical axis from a spherical mirror having a focal length 25cm.At what distance measured along the optical axis from the concave mirror should a plane mirror (perpendicular to principal axis) be placed for the image it forms (due to rays falling on it after reflection from the concave mirror)to coincide with the point source????
