I understand roughly that Rayleigh scattering occurs when white light encounters particles smaller than the wavelength of visible light, and short wavelengths are preferentially scattered.
I'm wondering if this phenomenon is particular to electromagnetic radiation (e.g. if discrete energy quanta play an essential role). It doesn't obviously seem like it based on the collision models I've seen—so my next question is whether you could set up an analogous phenomenon in a wave pool using water waves.
I imagine generating "white light" in the form of a superposition of waves of many frequencies, with physical scattering obstacles of roughly the same size as the waves. Would you be able to see backscattered higher frequency combinations separated from the lower frequency waves that persist past the scattering obstacles? What kind of pool scale/scattering density/obstacle size would you need to be able to see this macroscopically?
