Question

write the short note on ranibow formation​

Answer 1

Answer:

A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

Answer 2

Answer:

• 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 behind us and the water droplets falls infront 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).

• The water drops again refracts the different colours, when it comes out from the raindrop.

• After leaving this different colours from the raindrop as rainbow, reach our eye. Thus, we see a rainbow.
