Diffuse reflection is characterized by reflecting light in which way?

• A. a non-reflective or uneven surface
• B. a perfectly smooth mirror surface
• C. a transparent medium
• D. reflects light in many directions from a rough surface

Answer: (A)

Diffuse reflection occurs when light hits a rough surface, causing the reflected rays to scatter in many directions. Each tiny patch on the surface has a different orientation, so instead of a single reflected beam, the light is spread out, giving a matte appearance. This contrasts with a perfectly smooth surface, where light reflects in one direction (specular reflection). A non-reflective or uneven surface isn’t about this scattering behavior, and a transparent medium involves transmission, not the direction of reflection. So the hallmark of diffuse reflection is light being reflected in many directions from a rough surface.
