Intensity of scattered light is proportional to the fourth power of the wavelength of the incident light, provided the diameter of the scattering particle are smaller than the wavelength of the incident light.
i.e. begin mathsize 14px style straight I space equals 1 over straight lambda to the power of 4 end style
The scattered intensity is maximum for shorter wavelengths.
