Splitting white light into different colours is an optical phenomenon called Dispersion.
DISPERSION
light rays
The bending of light rays so they focus on the retina is called refraction.
A birefringence is a splitting of a ray of light into two parallel rays of perpendicular polarization by passage through an optically anistropic medium.

A lens that forms images by refracting light rays together is called what?
It is called a beam.
I believe you want to ask: what are the so-called "bounced-off" rays of light called? If so, the simplest answer would be: "reflections".
The bouncing of light is called reflection.
The splitting of white light into seven different constituent colours is called dispersion
Between visible light and X-rays there is ultraviolet light.
Focussing.
