Q. The blue colour of the water of the sea is due to :
A) Refraction of the blue light by the impurities in sea water
B) Reflection of blue light by sea water
C) Scattering of blue light by sol paricles
D) Absorption of other colours except the blue colour by water molecules
Explanation
(c)
The scattering $\propto \frac{1}{\lambda^{4}}$. Thus, scattering of blue light (shorter wavelength) is more.
