SUMMARY
The discussion clarifies the distinction between scattering and diffusion in the context of electromagnetic waves. Scattering occurs when a photon, such as a gamma ray, interacts with an electron, resulting in a change of direction, which is a singular event. In contrast, diffusion involves numerous interactions where light passes through a medium like fog, leading to a collective effect of many small scatters. The key takeaway is that scattering is characterized by fewer, more significant interactions, while diffusion is defined by a high frequency of interactions with minimal separation.
