PhysicsEasysingle choice

On decreasing the wavelength of incident light from $8000 \overset{\circ}{A}$ to $4000 \overset{\circ}{A},$ the intensity of the scattered light in Rayleigh scattering will become _____ times the initial scattered intensity.

Options:

Answer:

Solution:

$I \propto \frac{1}{λ^{4}}$

$\Rightarrow \frac{I_{f}}{I_{i}} = {(\frac{λ_{i}}{λ_{f}})}^{4}$

$= {(\frac{8}{4})}^{4} = 2^{4} = 16$
