16

Reason — According to Rayleigh scattering, the amount of scattering is inversely proportional to the fourth power of the wavelength of the light.

We know,

λ_violet = 4000 Å and

λ_red = 8000 Å.

According to Rayleigh scattering,

$\dfrac{\text{Intensity of scattering of violet}}{\text{Intensity of scattering of red}}$ = $(\dfrac{λ${red}}{λ{violet}})^4

So,

$\dfrac{\text{Intensity of scattering of violet}}{\text{Intensity of scattering of red}}$ = $(\dfrac{8000}{{4000}})^4$ = 2⁴

= 16

Hence, Intensity of scattering of violet = 16 time Intensity of scattering of red.
