There isn't a specific scientific name for "bouncing light" itself. Instead, the scientific term depends on how the light is bouncing:

* Reflection: This is the most common way light bounces. It occurs when light waves strike a surface and change direction. There are two types:

* Specular reflection: This is when light bounces off a smooth surface, like a mirror, in a predictable way.

* Diffuse reflection: This is when light bounces off a rough surface, like a piece of paper, in many different directions.

* Scattering: This is when light waves are deflected by particles in a medium, like air or water. It causes light to change direction in an unpredictable way, making things appear blurry or hazy.

* Refraction: This is when light waves bend as they pass from one medium to another, like from air to water. It's why objects appear to be in different locations when submerged in water.

So, depending on the context, you might refer to "reflection," "scattering," or "refraction" to describe how light is bouncing.
