How does the intensity of scattered light depend on the wavelength of incident light? State conditions when this dependence holds.

The fourth power of the wavelength is discovered to be inversely related to the intensity of scattered light. When the size of the air molecules is less than the wavelength of incoming light, this relationship holds.
