The discussion centers on the relationship between particle size and electromagnetic (EM) radiation scattering, specifically addressing how particle size influences diffraction effects. It is established that when light interacts with non-fundamental particles, the scattering is dependent on the particle's size relative to the wavelength of the light. The phenomenon is explained through concepts such as the impact parameter and cross-section for interaction, with Rayleigh scattering mentioned as a relevant example. The basis for particle size measurements is linked to the diffraction of light at specific angles and intensities based on particle dimensions.
