PhysicsEasysingle choice

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

Options:

Answer:

Solution:

We know from Rayleight's law of scattering

$I \propto \frac{1}{λ^{4}}$

So, $\frac{I_{1}}{I_{2}} = {(\frac{λ_{2}}{λ_{1}})}^{4}$

$\Rightarrow \frac{A}{I_{2}} = {(\frac{330}{880})}^{4} = {(\frac{3}{8})}^{4} = \frac{81}{4096}$

$I_{2} = \frac{4096}{81} A = (50.57) A$
