Picto-quiz: lenses and images

Let's apply the concepts introduced in a previous presentation, where we used ray tracings to find images produced by converging and diverging lenses.

Pair up in groups of two or three, pick up a whiteboard, and for each of these real-world examples, decide whether this is a converging or diverging lens, producing a real or virtual image, and choose the corresponding ray tracing diagram (or diagrams) from your worksheet.

For this image produced by a water glass, is this produced by a converging or diverging lens? Is this a real or virtual image? Which ray tracing(s) ((1)-(10)) best match(es) this?
