On which does the scattering of light depend?

Let $S_1$ be the amount of Rayleigh scattered light of wavelength $\lambda_1$ and $S_2$ that of light of wavelength $\lambda_2$ from a particle of size $a$. Which of the following statements is true?

In a given direction,the intensities of the scattered light by a scattering substance for two beams of light are in the ratio of $256:81$. The ratio of the frequency of the first beam to the frequency of the second beam is:

What is scattering of light?

If the scattering intensity of a liquid is $8 \text{ units}$ at a wavelength of $500 \text{ nm}$, then the scattering intensity at a wavelength of $400 \text{ nm}$ will be approximately: (in $\text{ units}$)
