Content :

The rainbow is an heavenly unique beautiful seven colurs in the sky .

Rainbow is always observed on the sky whenever the rain is over. It is arch shaped with seven colours .

Rainbow is glamour and brilliant sight to behold.

Rainbow is an arc of colours appearing opposite the sun as a result of the refraction of sunlight in the rain. Explain to the kids that a rainbow is that coloured light seen in the sky when rays of the sun strikes falling raindrops.

The light from the sun, though bright, does not appear to have colours when we look at it. But light is actually made up of all colours of the colour spectrum——— which are red,orange, yellow, green, blue, indigo, and violet. ( ROYGBIV) When all of these lights come together as one, we get white light. So the white light is the sun we see when we look up.

So, rainbow is formed when the white light, that is sun, passes through water droplets in the sky. The water droplet splits the white light, causing all the seven colours to appear, hence, rainbow is formed.

Note that rainbow appears when water comes in contact with sun. Therefore, rainbow is usually seen when the sun is out during rainfall or when the sun comes out of the clouds immediately after rainfall, meaning there is still a lot of moisture in the atmosphere.

Rainbows are formed when light shines through water, like the sun shines through the rain. This light is bent and reflected, like reflection in a mirror. This reflection brings out all the amazing colours of the rainbow.

Rainbow can be seen in mist, fog, spray and dew.
