Formation of Rainbow

 

  • A rainbow is a natural spectrum that usually appears after a rainfall, always in a direction to that of the sun.
  • The sunlight gets dispersed by tiny droplets of water in the atmosphere, which act like small prisms.

Sometimes, when you look at the sun through a water fall or a fountain (even on a sunny day), you see the rainbow. Here again the water droplets refract sunlight.
