Hi wyzgowski7-ga, and thanks for your question. First, here's a good tutorial on lenses and mirrors: ://www.google.com/url?sa=U&start=2&q=http://www.rowan.edu/colleges/las/physicsandastronomy/LabManual/labs/LensesAndMirrors.pdf&e=9707 On the first page of this document, we have the equation for magnification: m = i / p, where m is the magnification, i is the image distance, and p is the object distance. From this, we have m = i / p = 16mm / 8mm = 2 2 x 4mm = 8mm, so the height of the image is 8mm. Please feel free to request clarification. -welte-ga
