Homework Help: Physics

Why is it necessary to collimate the light source before using the prism to disperse the light?

A. If white light enters the prism with different angles, some of the blue light will exit the prism with the same angle as the orange light.

B. If white light enters the prism with different angles, some of the blue light will exit the prism from the same position as the orange light.

C. Both of these.

D. None of these.

I'm leaning towards B on this question because if the light wasn't collected in parallel lines then wouldn't it just spread out and pass through the prism without splitting in to the spectrum of colors?
