Question
What is a scattering of light? Describe a natural phenomenon based on it.
Answer
Scattering: Scattering is the process of absorption of light energy and then re-emission of light energy by the dust particles and air molecules.
The sky looks blue due to the scattering of sunlight by the molecules of the atmosphere. When sunlight passes through the atmosphere, then nitrogen and oxygen molecules present in the atmosphere absorb a part of sunlight and re-emit it. As the wavelength of the blue colour is shorter, it scatters more than any other colour light. Hence the sky looks blue.
