Which best describes diffuse reflection on a matte surface?

• A. Reflected in many directions
• B. Focused in a single direction
• C. Completely absorbed
• D. Transmitted through

Answer: (A)

Diffuse reflection happens when light hits a rough, matte surface whose tiny facets are oriented in many directions. Each microfaceted patch reflects light in its own direction, so the overall reflected light spreads out rather than traveling in a single beam. That scattering gives the surface its even, non-glossy appearance from many viewing angles. In contrast, focused reflection comes from smooth, mirror-like surfaces; complete absorption means no light is reflected at all, and transmission means light passes through the material rather than reflecting off its surface.
