Question

Describe the difference between diffuse reflection and regular (or specular) reflection. Explain what causes light rays to undergo diffuse reflection. Which one of the following diagrams depicts diffuse reflection? ___ True or False: When a beam of light undergoes diffuse reflection, individual rays within the beam do NOT follow the law of reflection. Explain your answer. For each of the five surfaces given below, draw normal lines. Consider the diagram at the right of five rays of light approaching a microscopically rough surface. For each incident ray, estimate the normal line and draw the corresponding reflected ray of light.

Explanation / Answer

1. Specular reflection follows laws of reflection but diffuse reflection does not follow laws of reflection. In diffuse reflection, incident ray is reflected at many angle rather than just one angle in specular reflection.

2. Surface roughness causes specular reflection.

3. ans b.as it does not folllow laws of reflection.

4.False because general scattering involve in diffuse scattering where laws of reflection are violated.
