# Photon Attenuation

I know in scattering theory that a wave can be attenuated when it interacts with a dielectric sphere, it is partially scattered, partially absorbed. So, the scattering light has less flux density than was incident.

However, if we use wave-particle duality then the same should be true for a photon ?

Or do we assume due to it being flux density that it is a large mass of photons over a given area, and then some photons are absorbed and some not, in a probabilistic manner ?

From what I understand I always assumed that photons were either absorbed or not, and weren't ever attenuated is that correct ? If a photon is attenuated that would mean it would have to change wavelength due to the Planck-Einstein relation ?

Any help would be much appreciated.

Thanks.
