Light through objects

  • Objects that do not allow light to transmit or pass through are called opaque.
  • Glass and other see-through objects are transparent because light can be transmitted through them.
  • Translucent objects scatter light. So not all the light is transmitted, such as in privacy windows in bathrooms and walk-in showers.
