A DIVERGING lens has a focal length of 35 cm. (a) Find the image distance when an object is placed 48 cm from the lens. (b) Is the image real or virtual magnified or reduced?

Answer:

In diverging lenses, image is always virtual. In this question image is reduced, just because object is behind the focus. In order to find the image distance we should know the height of object or image.
