Vedclass · Answer

(C) $1$. Sunlight undergoes scattering by atmospheric particles (Rayleigh scattering). This scattered light is partially polarized.$2$. Because the light from the blue sky is partially polarized,when viewed through a calcite crystal (which acts as a polarizer/analyzer),rotating the crystal changes the intensity of the transmitted light due to Malus' Law.$3$. Statement-$I$ is true because the sky light is polarized.$4$. Statement-$II$ is true because the polarization of sky light is indeed caused by scattering,and scattering is most effective for blue light (shorter wavelengths).$5$. Statement-$II$ provides the physical mechanism (scattering) that explains why the light is polarized,which is the reason for the observation in Statement-$I$.
