what is scattering of light
Answers
Answer:
The scattering of light is the phenomenon by which a beam of light is redirected in different directions on interacting with the particles present in the medium. The sky appears blue because the fine particles in the atmosphere scatter blue light the most among all the components of white light.
hope this helps u xD do follow me..
Answer:
Scattering occurs when light or other energy waves pass through an imperfect medium (such as air filled with particles of some sort) and are deflected from a straight path. The colors of light separate as the sun's rays pass through the atmosphere, and blue is the color that reaches us.
Explanation:
There are three different types of scattering: Rayleigh scattering, Mie scattering, and non-selective scattering.
Rayleigh scattering mainly consists of scattering from atmospheric gases. This occurs when the particles causing the scattering are smaller in size than the wavelengths of radiation in contact with them. This type of scattering is therefore wavelength dependent. As the wavelength decreases, the amount of scattering increases. Because of Rayleigh scattering, the sky appears blue, as in the picture below. This is because blue light is scattered around four times as much as red light, and UV light is scattered about 16 times as much as red light.
Mie scattering is caused by pollen, dust, smoke, water droplets, and other particles in the lower portion of the atmosphere. It occurs when the particles causing the scattering are larger than the wavelengths of radiation in contact with them. Mie scattering is responsible for the white appearance of the clouds, as seen below.
The last type of scattering is non-selective scattering. It occurs in the lower portion of the atmosphere when the particles are much larger than the incident radiation. This type of scattering is not wavelength dependent and is the primary cause of haze.
