1. Is the image projected on a movie screen real or virtual? What about the image of yourself seen in a bathroom mirror?


2. Hold a shiny spoon in front of you. What differences do you notice about the image of your face seen in the convex and concave sides?


3. Where are the images formed by each side of the spoon? In front or behind the spoon? (Try the parallax method. Look at the image of an overhead light. Hold the tip of a pencil where you think the image is. Move your head from side to side. If the image and pencil tip appear to move relative to each other, adjust the position of the pencil back and forth until they appear as one)
