Reference Guide

How Materials Interact with Light

  • Transparent. Light passes straight through (clear glass, water).
  • Translucent. Some light passes through, rest is scattered (frosted glass, tissue).
  • Opaque. No light passes through (wood, rock, cardboard).

Shadows and Light

  • A shadow forms when an object blocks light.
  • Opaque objects make dark, sharp shadows.
  • Translucent objects make faint or fuzzy shadows.
  • Transparent objects make no shadow at all.
