Why
do
we
see
colors
?
1
.
-
Visible
light
from
the
sun
comes
to
Earth
as
light
,
traveling
through
space
in
the
form
of
waves
.
2
.
When
light
waves
are
refracted
as
sunlight
passes
through
raindrops
,
their
wavelengths
are
separated
,
and
we
see
them
as
different
.
3
.
-
A
triangular
piece
of
glass
or
plastic
called
a
bends
light
and
separates
it
into
the
wavelengths
that
make
up
white
light
.
4
.
-
Light
passing
through
the
slits
of
a
is
refracted
,
and
the
wavelengths
that
make
up
the
light
can
be
seen
.
5
.
-
Sunlight
striking
an
object
may
be
refracted
,
reflected
,
or
.
6
.
-
The
light
that
is
reflected
by
an
object
determines
the
of
that
object
.
How
many
kinds
of
light
are
there
?
7
.
-
Energy
from
the
Sun
travels
in
many
types
of
waves
,
the
contains
the
full
range
of
these
wavelengths
.
8
.
-
The
spectrum
is
arranged
from
long
waves
,
with
the
amount
of
energy
,
to
short
waves
with
the
amount
of
energy
.
