A rainbow occurs at the end of a storm, when the sun begins to shine white the air is still filled with raindrops. When the sunlight passes through the millions of water drops in just the right way, the white light breaks up and scatters into the many colors of the spectrum.
If you are looking in the direction of the drops with the sun to your back you will see a rainbow of color arched across the sky in the beautiful bands of orange, red, green and blue, with red at the top of the arch and violet at the bottom.
The colors blend into each other so that we rarely see more that four or five colors in a rainbow.
A rainbow disappears as soon as there are no longer any raindrops in the air. You can make a rainbow yourself on a sunny day. Turn the lawn sprinkler on. Stand with our back to the sun and look at the spray. You should be able to see a rainbow.
