A diverging lens produces magnification of 0.6 for an object
of 5 cm height. The distance between object and image is 4 cm.
Object is perpendicular to the optical axis. Using ray diagram lo-
cate the position of lens and focus.
A plane mirror is kept at 5 cm from the lens on the other side of
object. Draw the image in the mirror using ray diagram.
Please do not draw any images that may get created further.

Answer:
Introduction (Refraction and Lenses)
Lenses use refraction to produce images of objects. Optical instruments, such as telescopes or cameras, and your eyes work this way.
The surface of the lens in the diagram below is shaped so that spherical
wave fronts of light coming from a point, F, called the focal point,
emerge as parallel wave fronts (so-called plane waves).
