17N.3.SL.TZ0.c.i
A magnifying glass is constructed from a thin converging lens.
The object is replaced with an L shape that is positioned 0.30 m vertically above the principal axis as shown. A screen is used to form a focused image of part of the L shape. Two points P and Q on the base of the L shape and R on its top, are indicated on the diagram. Point Q is 10.0 m away from the same lens as used in part (b).
On the diagram, draw two rays to locate the point Q′ on the image that corresponds to point Q on the L shape.
