The Attempt at a Solution

EDIT: I believe the answer is all letters will be the same because slide projectors produce images that are the same size, virtual and upright. Could someone tell me if I'm right or wrong? Thanks.

A slide projector projects images that are formed on some kind of screen. Can you form a virtual image on a screen?

I do believe virtual images can be shown on a screen, but I think the image would be real, because the light comes together or something like that?

 

[G01]

A virtual image cannot be formed on a screen. In a virtual image, the light seems as if if comes from a certain point. The image is at this point. Since the light isn't actually there, a screen placed there will not show an image.

So what type of image do you want to form in order for it to appear on a screen and will it be upright or upside down?
