a. If I have a magnifying glass that has two different lenses on it, how can I determine which lens has a longer focal length, and is there a place where you can see a real image in one lens and a virtual image in the other? b. How can I use parallax to confirm that the real image that can be seen in the magnifying glass is in front of the lens? - which is between the lens and the eye
