Practice Question
1.Describe how you could tell from a ray diagram if you were looking at specular or diffuse reflection
Specular reflection will have a regular pattern of incident and reflected light rays
Diffuse reflection will be a random scattering of the light rays on the ray diagram.
2. State the name of the types of surface that specular reflection occurs on
Smooth, shiny surface
3. State the name of the type of surface that diffuse reflection occurs on.
Rough, matt surfaces
