A concave mirror of focal length 'f' is placed at a distance of 'd' from a convex lens of focal length . A beam of light coming from infinity and falling on this convex lens-concave mirror combination returns to infinity. The distance 'd' must equal : (a) f + f (c) 2f + f (b)-f + f (d) -2f + f A concave mirror of focal length 'f' is placed at a distance of 'd' from a convex lens of focal length .
