📚 Quick Study Guide

  • 🌈 Light is part of the electromagnetic spectrum. Visible light is the portion we can see, which consists of different wavelengths that we perceive as colors.
  • 🍎 Color in nature often results from the interaction of light with different substances. Some materials absorb certain wavelengths and reflect others, resulting in what we see as color.
  • 🦋 Iridescence is a phenomenon where colors change depending on the angle of viewing due to the structure of the surface, such as in butterfly wings.
  • 🌿 Pigments are substances that give materials color by selectively absorbing and reflecting light. Chlorophyll, for instance, gives plants their green color.
  • ✨ Bioluminescence is the production and emission of light by a living organism. It involves chemical reactions, often using luciferase enzymes.
