Rain
bows
happen when sunlight and rain combine in a very specifc way.
The
beams
of sunlight separate into the colors we see in the rainbow as they
enter a raindrop.
Sunlight is actually made up of different colors that we don’t
usually see. When a beam of sunlight comes down to Earth, the light is white.
But, if the light beam happens to hit raindrops on the way down at a certain
angle
, the different colors that make up the beam separate so that we can
see them in the form of a rainbow.
The angle for each color of a rainbow is
different, because the colors slow down at different
speeds
when they enter
the raindrop. The light exits the raindrop in one color, depending on the angle
it came in, so we see only one color coming from each raindrop. Light at
different angles coming through many raindrops form the rainbow that we see,
in
stripes
of red, orange, yellow, green, blue, indigo and violet.
