How do you calculate the magnification of the image?
M = hi/hd = -di/do
So I took 1.0/7.0 = -0.14. Is this correct?
Focal Length: 5 cm
Object Height: 7 cm
Object position [cm]: Record
Image height [cm]: Record
Image position [cm]: Record
Calculate the focal point using object and image position [cm]
Calculate the % error between the focal point and the calculated focal point
Calculate the magnification of the image: 40.0
1.0
5.7
4.989059081
0.218818381
-0.14
