It is stated that red light bends less than blue light as white light is dispersed through a glass prism. I understand that red light travels faster within the glass because of its higher wavelength, but shouldn't a faster velocity mean it bends away more from the normal of exit out of the prism than blue light?

What is the effect of velocity of a wave on how it bends relative to the normal? I've seen that when a wave passes from less dense to more dense medium, it slows down and bends towards the normal, so I am using this knowledge to assume a slower wave bends more towards the normal. Am I correct in thinking this?
