Why do we see the colors of the electromagnetic spectrum?

• light goes straight through something and some parts of the light slow down, spreading out the light into colors

• light goes straight through something and some parts of the light speeds up, spreading out the light into colors

• light bends when traveling through something and some parts of the light slow down, spreading out the light into colors

• light bends when traveling through something and some parts of the light speeds up, spreading out the light into colors
