The process of light soaking into a surface and making it hotter is called absorption.

Here's why:

* Absorption: When light strikes a surface, some of it is absorbed by the material. This absorbed light energy is converted into other forms of energy, primarily heat.

* Reflection: Some light bounces off the surface, which is called reflection.

* Transmission: Some light passes through the surface, which is called transmission.

The amount of light absorbed, reflected, and transmitted depends on the properties of the material. Darker materials tend to absorb more light, while lighter materials reflect more.
