Specular reflection occurs when rays reflect off a smooth surface. The rays striking the surface at a given incident angle will all reflect off the surface at the same angle. Diffuse reflection occurs when rays reflect off a rough surface. The rays striking the surface will reflect off the surface at different angles.

#### Work Step by Step

There are differences between specular reflection and diffuse reflection. Specular reflection occurs when rays reflect off a smooth surface. The rays striking the surface at a given incident angle will all reflect off the surface at the same angle. Diffuse reflection occurs when rays reflect off a rough surface. The rays striking the surface will reflect off the surface at different angles.
