When sunlight is scattered by atmospheric atoms and molecules, the amount of scattering of light of wavelength

\mathrm{440}\,\,\mathrm{nm}

A

. The amount of scattering for the light of wavelength

\mathrm{660}\,\,\mathrm{nm}

is approximately

View answer and explanation

Correct option: D

\frac{A}{5}

Option D (

\frac{A}{5}

) is correct because the scattering of light is inversely proportional to the fourth power of the wavelength, according to Rayleigh's scattering law.
