Question

Figure shows a thin converging lens for which the focal length is 5.00 cm. The lens is in front of a concave spherical mirror of radius R = 30 cm. If the lens and mirror are 20.0 cm apart and an object is placed 15 cm to the left of the lens, determine the approximate distance of the final image from lens. (in cm).

Options

A.

5.3m

B.

4.6m

C.

6.1cm

D.

12.7 cm

Solution

1v-1-15=151v=15-115v=7.5v'=12.51v'-112.5=1-151v'=225-1151v'=12-10150v' = 75 cm v'' = –95 cm1v''+195=15 v'' = 5.3cm
