The moon does not produce its own light. Moonlight
is sunlight that has bounced off the moon!
When light hits a surface, some
of it bounces off or is reflected.
Light can pass through transparent
objects like glass but cannot pass through opaque
objects like wood. Things look strange underwater,
because light travels from them in a different
way. Light moves more slowly through water than
it moves through air. As the beam of light enters
the water, it slows down and bends. As it re-enters
the air the light beam speeds up and bends back
again. This is called refraction.
materials allow light to travel through them.
We can see clearly through transparent materials
like water and glass.
objects do not let light travel through them.
These objects create shadows on a sunny day.
materials allow light to come through but we cannot
see through it.
