A rough surface tends to do which of the following in terms of light and color?

• A. Reflects more light and therefore is a more intense color
• B. Appears lighter
• C. Absorbs less light and therefore appears brighter
• D. Absorbs more light and therefore appears darker

Answer: (D)

When light meets a rough surface, it hits many tiny facets oriented in different directions. This creates diffuse reflection, scattering light in all directions rather than bouncing it off in one strong, mirror-like beam. That diffusion means less light is redirected toward your eye from any given angle, so the surface looks less bright. Additionally, the rough texture can cause light to take longer paths within the material, increasing absorption. The combination of scattered light and greater absorption makes the surface appear darker.
