Bending Light Experiments
Light travels through the air in straight lines. If
it didn't there wouldn't be any shadows.
The only way we can see
an object is if rays of light hit the object and it then reaches
our eyes.
This is why we can’t see things in
the dark. The objects are still there but there is no light to reveal
them. 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.
