Question

2. A bumpy, rough surface is also referred to as a
(diffused/irregular)surface
​

Answer 1

Here you are buddy. The way that light bounces off the surface of an object follows a strict law called the Law of Reflection, which says “The angle of incidence equals the angle of reflection”. The Law of Reflection tells us that when light strikes a reflecting surface, the reflected light ray bounces off the surface at the same angle as it strikes the surface. If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection.

Specular (Regular) Reflection

Regular reflection is where light is reflected off a smooth surface. So, if incident rays are parallel, reflected rays are also parallel.

Diffuse (Irregular) Reflection

Irregular reflection occurs when light strikes a rough surface, as shown here. The Laws of Reflection still hold but because the normal of the surface are all on different angles, light is scattered or diffused.
