If a glass prism can cause white light to be dispersed,can a glass block or any other transparent and smooth surface do that too?

Trying to clear my doubts before my test.

Thank you!

You need to have the same situation that you do with a prism: surfaces that aren't parallel, so that the refraction and dispersion are not cancelled out. So if by block you mean a cube or rectangle, you won't see it with the parallel surfaces, but you could with the ones that are 90º to each other.

For this and the other questions you have asked, you need to understand refraction.
