When light hits a material, it may get absorbed by the material, transmitted through the surface, or reflected. Most materials showcase a mixture of these properties.
In class, we discussed ideal specular reflection, which is a type of surface reflection that reflects an incident ray into a single outgoing direction. This reflection is often used to describe ideal mirror-like reflection of lights (in fact, the word specular means mirror in Latin).
Specular reflection follows the Laws of Reflection, the angle of reflection is equal to the angle of incidence.
