QUESTION:
Why do you put slides into an old-fashioned slide projector upside down?
ANSWER:Step 1 of 2
A convex mirror is used by old-fashioned slide projectors to reflect the slide's picture onto the screen. A real and inverted image of the slide is produced by the convex mirror on the screen projector. We must flip the slide because we want to create an image of it that is upright.
