Question

A 5.00 cm tall object is placed 4.25 cm from a lens and produces an image that is 3.00 cm behind the lens. What is the magnification of the lens?-1.42-0.7061.420.706

Answer 1

Let's define some variables:

M: magnification

DO: distance of the object; DO = 4.25 cm

DI: distance of the image; DI = -3 cm (negative because it's behind the lens)

M = -DI/DO

M = -(-3)/4.25

M = 0.706
