The splitting of light rays into different colors is called dispersion. This occurs when light rays pass through a prism or other refractive medium, causing the different wavelengths of light to refract at different angles and separate into the colors of the rainbow.
Light rays coming in are called incident light rays.
The light rays that bounce back are called reflected light rays.
A broad bundle of light rays is called a beam.
Solar energy
The point where light rays meet is called the focal point.

A broad bundle of light rays is called a beam.
The point where light rays meet is called the focal point.
A collection of rays of light is called a beam or a ray bundle.
The bouncing of light rays is called reflection. When light rays strike a surface and return back in the same direction, it is known as reflection.
The splitting of light into a range of colors is called dispersion. This occurs when light interacts with a prism or a diffraction grating, causing the different wavelengths of light to separate and form a spectrum of colors.
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 light rays that leave a mirror are called reflected rays. They are the result of light bouncing off the mirror's surface at an equal angle to the incident angle.
A bundle of light rays is called a "beam" or "ray bundle."
When light rays are bent, they are called refracted. Refraction occurs when light passes through different mediums of different optical densities, causing the light rays to change direction.
