Answer to Question #2944 in Optics for dave

Question #2944
A converging lens has a focal length of 25.5 cm. If it is placed 72.5 cm from an object, at what distance from the lens will the image be? What is the magnification of the lens?
Expert's answer
From the formula:
/cgi-bin/mimetex.cgi?%5Cfrac%7B1%7D%7Bf%7D%20=%20%5Cfrac%7B1%7D%7Bd_1%7D%20+%20%5Cfrac%7B1%7D%7Bd_2%7D

1/25.5 = 1/72.5 + 1/d2
d2 = 1848.75 / 47 = 39.34
The magnification is m = - 39.34/25.5 = - 1.54
