Answer:
THE FORMATION OF RAINBOW IS DUE TO THE DISPERSION OF WHITE LIGHT.
THE PROCESS IS CALLED REFRACTION.
HOW IS A RAINBOW FORMED?
ANS -A rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops.
It is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere.
Always it formed in the direction opposite to the sun.
To see a rainbow, the sun must be behind us and the water droplets falling in front of us.
When a sunlight enters into a spherical rain drop, it is refracted and dispersed. The different colours of light bent in different angles.
When different colours of light fall on the back inner surface of drop, it (water drop) reflects (different colours of light) internally (total internal reflection).
