How rainbows are formed

Rainbows are formed
when light from the
sun is scattered by
water droplets (e.g.
raindrops or fog)
through a process
called refraction.

How can we see a rainbow

They are reflected from the back
surface of the raindrop, and refracted
again as they exit the raindrop and
return to our eyes.

When can we see a rainbow?

We see rainbow in the sky
only after rainfall due to
dispersion of sunlight by
the tiny water droplets of
rain present in the
atmosphere.
