How Are Rainbows Formed?

            How  Are  Rainbows  Formed?

   Rainbows happen when sunlight and rain combine 
                      in a very specific way.

The beams of sunlight separate into the colours we see
    in the rainbow as they enter a raindrop. Sunlight is
actually made up of different colours 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 the
   raindrops on the way down at a certain angle, the 
different colours that make up a beam, separate so we can                 
         see them.

As you look into the sky, wavelengths of light associated 
   with a specific colour arrive at your eye. When you look
up to the sky you will also see ROYGBIV known as red,
    orange, yellow, green, blue, indigo, and violet. A rainbow 
        has seven colours because water droplets in the 
     atmosphere break sunlight into seven colours.
    You can see a rainbow when the sun is located right      
           behind you.
