Key Concepts and Definitions:

  • Light: A form of energy that enables us to see objects.
  • Shadow: A dark area produced by an object coming between a source of light and a surface.
  • Reflection: The bouncing back of light from a surface.
  • Transparent: Materials that allow light to pass through them (e.g., clear glass).
  • Translucent: Materials that allow some light to pass through them but scatter it (e.g., frosted glass).
  • Opaque: Materials that do not allow light to pass through them (e.g., wood).
