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

-0.125.

Step-by-step explanation:

The previous explanation is right except for that it doesn't take into account that the -3.09 is negative – therefore, the positive answer is incorrect.

-0.125 is correct on Acellus.

Answer 2

Answer: 0.125

Step-by-step 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
