A point source `S` is placed at distance of `15` cm from a converging lens of focal length `10` cm . Where should a (i) concave mirror (ii) convex mirror of focal length `12` cm be placed so that real image is formed on object itself.

A point source S is placed at a distance of 15 cm from a converging lens of focal length 10 cm on its principal axis. Where should a diverging miror of focal length 12 cm be placed to that a real image is formed on the source itself.

(a) A point source S is placed at a distance of 15 cm from a converging lens of focal length 10 cm on its principal axis, where should a diverging mirror of focal length 12 cm be placed so that a real image is formed on the source itself? (b) A diverging lens of focal length 20 cm and a converging mirror of focal length 10 cm are placed coaxially at separation of 5 cm. Where should an object be placed so that a real image is formed at the object itself? (c) A converging lens of focal length 12 cm and a diverging mirror of focal length 7.5 cm are placed 5.0 cm apart with the principal axis coinciding where should an object be placed so that its image falls on itself?
