    When--sunlight is scattered by atmospheric    atoms and molecules the amount of      scattering of light of wavelength 880nm is A.     Then, the amount of scattering of light of wavelength 330 nm is approximately

    A) 10 A                      

    B) 20 A  

    C) 40 A                      

    D) 50.5 A

    Correct Answer: D

    Solution :

    We know from Rayleigh's law of scattering                      \[R=R'-{{R}_{0}}=40-10=30\Omega \] So,       \[{{I}_{1}}\] \[E=k{{I}_{1}}\]        \[{{\text{I}}_{\text{2}}}\text{.}\]               \[V=k{{I}_{2}}\]
