Question

A 24.8 tall object is placed in front of a lens, which creates a -3.09 cm tall image. What is the magnification?

Answer 1

Answer: 0.125

Explanation:

Given that the

Object height U = 24.8 cm

Image height V = 3.09 cm

Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.

M = V/U

Substitute V and U into the formula above.

M = 3.09/24.8

M = 0.125

Magnification is therefore equal to 0.125 approximately
