What is the FOCUS?
The focus is where light waves all converge on one point (the focus) to form a visible image.

What does a CONVEX lens do?
A convex lens focuses light waves to a focus. However, they can also magnify or diminish the image.

What happens to light when is goes through a prism?
The light slows down and refracts, meaning that it bends, because of the decrease in speed.
