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 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 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?

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 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.

An illuminated object is placed at a distance of 20 cm from a converging lens of focal length 15 cm. The image obtained on the screen is:

The focal length of a concave mirror is 12 cm . Where should an object of length 4 cm be placed so that a real image of 1 cm length is formed ?

A diverging lens of focal length 20 cm is placed coaxially 5 cm toward left of a converging mirror of focal length 10 cm. Where would an object be placed toward left of the lens so that a real image is formed on object itself.
