Alexis is studying how lenses work. She looks through a magnifying glass and through the peephole of a door. Which best describes a difference between the lenses used in these two devices?

A magnifying glass uses a converging lens. Depending on how far the object is from the lens, it can form an upright virtual image or an inverted real image. A door peephole uses a diverging lens, which forms an upright image, so the best choice is that the magnifying glass can produce both upright and inverted images while the peephole produces only upright images.
