The nickel's image has four times the diameter of the nickel when the lens is 2.70 cm from the nickel. Determine the focal length of the lens?
Step 1. The object distance, from the nickel to the lens, is p= 2.70 cm
Step 2. Since the image is four times the size as ...
This solution provides step-by-step solutions for using distance, magnification, to find image distance and focal length.
