Question

According to the Rayleigh's law of scattering, the intensity of light $\left(I\right)$ and the wavelength$\left(\lambda \right)$ are related as :

• A. $I\propto {\lambda }^2$
• B. $I\propto \frac{1}{{\lambda }^4}$
• C. $I\propto {\lambda }^4$
• D. $I\propto \frac{1}{-{\lambda }^{-2}}$

Answer 1

The correct option is B $I\propto \frac{1}{{\lambda }^4}$

$\begin{array}{c}\text{According to the Rayleigh's law of scattering,}\\ \text{the Intensity of light}\left(I\right)\text{and the}\\ \text{wavelength}\left(\lambda \right)\text{are related as}\\ I\propto \frac{1}{{\lambda }^4}\\ \text{so option}B\text{is correct.}\end{array}$
