उत्तर
Scattering is the phenomenon of change in the direction of light rays when they travel through Earth's atmosphere. Air is a mixture of gases, smoke, dust and very fine particles. As the rays of light fall on these particles, these rays are spread/scattered in all directions. It is a natural phenomenon which is observed on a daily basis.
