Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which scattering occurs when particles are very small compared to the wavelength of the radiation?
A
Mie
B
Nonselective
C
Rayleigh
D
All of the above
Explanation: 

Detailed explanation-1: -Rayleigh scattering (/ˈreɪli/ RAY-lee), named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation.

Detailed explanation-2: -When the scattering particles are much smaller than the wavelength of light, the scattering is known as Rayleigh scattering. It follows that in this regime light with a shorter wavelength is more greatly scattered than light with a longer wavelength.

Detailed explanation-3: -Rayleigh’s scattering law The amount of scattering is inversely proportional to the fourth power of the wavelength. This is known as Rayleigh scattering. As sunlight travels through the earths atmosphere, it gets scattered by the atmospheric particles.
