1.Scattering of light is the phenomenon in which light rays get deviated from its straight path on striking obstacles like dust or gas molecules, water vapours etc. Scattering of light gives rise to many spectacular phenomena such as Tyndall effect, and the red views of sunrise and sunset.When light passes from one medium to any other medium say air, a glass of water then a part of the light is absorbed by particles of the medium preceded by its subsequent radiation in a particular direction. This phenomenon is termed as a scattering of light

2.By measuring the intensity of the scattered light as a function of the scattering angle θ ( = 0◦ for unscattered light and = 180◦ for light scattered directly back into the laser)When the diameter of the dispersed particles is little smaller than the wavelength of light used. The longer-wavelength of light is more transmitted while the shorter-wavelength of light is more scattered.

3.Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day.

4.This is because the size of water droplets increases during the hot days due to the rise in temperature.

5.“Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. ... This is why sunsets are often yellow, orange, and red.
