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).
