Answer:
Option D
Explanation:
From Rayleigh's law of scattering, intensity
$I\propto\frac{1}{\lambda^{4}}$
$\therefore$ $\frac{I_{1}}{I_{2}}\propto\left(\frac{\lambda_{2}}{\lambda_{1}}\right)^{4}$
$\Rightarrow\frac{I_{1}}{I_{2}}=\left(\frac{330}{880}\right)^{4}=\left(\frac{3}{8}\right)^{4}=\frac{81}{4096}$
${I_{2}}=(\frac{4096}{81})$Å =(50.557)Å
