Fig. shows a plane mirror M placed at a distance of 10 cm from a concave lens L . A point object is placed at a distance of 60 cm from the lens. The image formed due to refraction by the lens and reflection by the mirror is 30 cm behind th mirror. What is the focal length of this lens ? .

A biconvex lens of focal length 15 cm is in front of a plane mirror. The distance between the lens and the mirror is 10 cm. A small object is kept at a distance of 30 cm from the lens. The final image is

A beam of light diverges from P on the axis of a convex lens and the after passing through the lens is reflected from the surface of a convex mirror. The reflected beam is brought to a focus by the lens at P itself. (a) Find the focal length of the lens. Given that the distance of the lens and the mirror is 10cm. The distance of P from the mirror is 30cm and the focal length of the mirror is 10cm.
