An object is placed in front of a converging lens with a focal length of 20.2 cm. For the object distance, find the image distance and the magnification.

Question

(a) 10.1 cm

location:

magnification:

Answer 1

(a) 1/20.2 = 1/10.1 + 1/f; f = 20.2/1 - 2); f = - 20.2 cm;

m = f/d = -20.2/10.1 = - 2
