Which of the following best describes diffuse reflection?

• A. Light reflects uniformly off a flat surface
• B. Light scatters in many directions from a rough surface
• C. Light reflects only at a specific angle
• D. Light is absorbed by the surface

Answer: (B)

Diffuse reflection occurs when light encounters a rough or textured surface, causing it to scatter in many different directions. This scattering effect is what differentiates diffuse reflection from specular reflection, where light reflects uniformly off smooth surfaces, such as a mirror or a still body of water. The unevenness of the rough surface disrupts the orderly reflection of light, leading to its dispersion and allowing objects to be seen from various angles. In practical terms, diffuse reflection is what allows us to see non-shiny surfaces, such as walls or paper. The light that bounces off these surfaces doesn't travel in a single, predictable direction but instead spreads out, making the illuminated area visible from multiple perspectives. This property is essential in our everyday perception of objects as it provides visibility under various lighting conditions.
