Specular reflection refers to the reflection of light off a smooth surface, where the angle of incidence is equal to the angle of reflection.
Diffuse Reflection: Diffuse reflection occurs when light reflects off a rough or uneven surface, scattering in different directions.
Incident Ray: An incident ray is the incoming ray of light that strikes a surface or boundary.
Reflected Ray: A reflected ray is the ray of light that bounces off a surface after striking it.
