Question

Check the correct statements on scattering of light.
$S_1$ : Rayleigh scattering is responsible for the bluish appearance of sky.
$S_2$ : Rayleigh scattering is proportional to $1/{\lambda }^4$ when the size of the scatterer is much less than $\lambda$ .
$S_3$ : Clouds having droplets of water (large scattering objects) scatter all wavelengths are almost equal and so are generally white.
$S_4$ : The sun looks reddish at sunset and sunrise due to Rayleigh scattering.

• A. $S_1$ only
• B. $S_1$ and $S_2$
• C. $S_2$ and $S_3$
• D. $S_1,S_2,S_3$ and $S_4$
