My dear children, most of you have seen the beautiful rainbow in the sky during the rain. A rainbow always appears in that section of sky where the sun rays fall directly. We can see the red color on the outer part of rainbow.When the sun shines through the rainfall we can see this arc of colors which is called rainbow . It has seven colors which are orange, yellow ,green ,blue ,indigo and violet . A rainbow appears when the sunlight enters in a droplet of water and gets reflected.
We can see only the upper part of rainbow because the bottom part is hidden. Actually it is round shaped but it looks like an arc in the sky.
Rainbows are the symbols of unity, peace and harmony .
