The correct option is D
none of these
An explanation for the correct option:
Scattering of light: When light passes from one medium to any other medium say air and 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 a scattering of light.
All the given options are correct because the sky appears blue due to the scattering of blue light due to the atmospheric particles.
Smoke and dust particles in the atmosphere cause a greyish appearance in the sky.
Red has the maximum wavelength in the visible spectrum, hence the velocity of red is more than another primary color
According to Rayleigh's scattering, the and hence the red color scatters the least.
When electromagnetic waves strike a matter, then scattering takes place as the particle on which the electromagnetic waves strike, removes the energy and re-radiates it in different directions.
