• Specular reflection implies that angle between the reflected beam and the normal to the surface equals the angle made by the incident radiation with the same normal. Reflection from highly polished and smooth surfaces approaches specular characteristics.
• In a diffused reflection, the incident beam is reflected in all directions. Most of the engineering materials have rough surfaces, and these rough surfaces give diffused reflections.
