Light & Shadows
A shadow is created when light does not pass through an object.
Light paths
- Light cannot bend around objects.
- Light can only travel in straight lines.
Materials

- Example: glass.
- Translucent materials: Let some light pass through.
- Example: tinted car windows.
- Opaque materials: Do not let light pass through.
- Example: wood.
Shadows
- When light passes in straight lines around opaque objects, the shadow formed is the same shape as the object
- E.g. shadow puppets.
