it is because rainbow is formed by the reflection of sunlight through the suspended rain drops in air after the rain..these tiny rain droplets act as prism and when light passes through these prism they refract into different colours..

Answer:
A rainbow requires water droplets to be floating in the air. That's why we see them right after it rains. The Sun must be behind you and the clouds cleared away from the Sun for the rainbow to appear.....
