* Reflectie: The light bounces off the surface. This is what allows us to see opaque objects. The amount of reflection depends on the material's surface properties. Shiny surfaces reflect more light, while dull surfaces absorb more.

* absorptie: The light is absorbed by the material, converting the light energy into heat. This is why dark-colored objects tend to get hotter in the sun than light-colored objects.

* verstrooiing: The light is scattered in different directions, rather than being reflected in a single direction. This is why we see through frosted glass, but not clear glass.

De relatieve hoeveelheden reflectie, absorptie en verstrooiing hangen af ​​van de eigenschappen van het materiaal, inclusief de kleur, textuur en compositie.

Samenvattend: When light hits an opaque material, it is reflected, absorbed, and/or scattered . The exact proportions of each process determine the material's appearance.
