Why are the slides inserted upside-down into the slide projector to see them right side up?
As light travels through a convex lens (used in most slide projectors), the light and slide image are turned upside-down. Therefore, in order to appear correctly on screen, the image must enter the lens upside-down, which would then be inverted by the lens to appear right-side up. **** Furthermore, they are reversed left to right. What applies to the vertical holds true for the horizontal. The above holds true for any type of slide projector that performs similar to a Kodak carousel. However, the cube projector (Bell & Howell?) was different because the image bounced off of a mirror before going through the lens. I believe those slides were inserted into the cube right side up, but backwards (left to right), but I'm not sure.
