Light
can
be
reflected
from
a
shiny
surface
like
a
mirror.
It
can
be
made
to
change
direction
by
the
shiny
surface.
If
a
ray
of
light
passes
into
an
object
with
different
density
-
like
air
to
water,
or
air
to
glass,
the
light
will
also
change
direction,
but
this
is
called
refraction.
The
light
is
slowed
up
as
it
passes
into
something
which
is
more
dense,
like
air
to
water,
just
like
we
go
slower
when
we
try
to
run
through
shallow
water.
The
light
bends
towards
the
normal.
Light
speeds
up
when
going
from
water
to
air,
(from
more
dense
objects
into
less
dense
objects).
This
will
refract
the
light
away
from
the
normal.
A
prism
refracts
light
rays
and
splits
up
white
light
into
the
colours
of
the
spectrum
-
red,
orange,
yellow,
green,
blue,
indigo
and
violet.
