creates a real image
Laws
The angle of reflection (r) = the angle of incidence (i)
The refelcted ray and incedent ray are on opposite sides of the normal
The reflected ray, the normal and the incedent ray all lie on the same plane

Type
Specular
Smooth and flat surfaces
All normals are perpendicular to the surface < i = < r
Diffuse
Rough surfaces
The normals are all facing different directions
< r are all different from each other
