Answer 2

Answer:

1) The rainbow is a spectrum of sunlight in nature.

2) The Rainbow is formed due to Dispersion of Sunlight by water droplets suspended in the atmosphere after rain.

3) This phenomenon is due to the combination of refraction of Sunlight by spherical water droplets. Which act as a prism and the total internal reflection takes place.

4) Parallel beam of Sunlight coming from sun getting dispersed at different angles of a deviation produced a cone of rays at the observers eye.

5) The rainbow, therefore appears as an arc of circle for an observer on the earth
