Radiography In gamma-ray radiography the mean free path of a pencil beam of mono-energetic photons is the average distance a photon travels between collisions with atoms of the target material. It depends on the material and the energy of the photons: $${\displaystyle \ell =\mu ^{-1}=((\mu /\rho )\rho )^{ … Ver mais In physics, mean free path is the average distance over which a moving particle (such as an atom, a molecule, or a photon) travels before substantially changing its direction or energy (or, in a specific context, other properties), typically … Ver mais • Scattering theory • Ballistic conduction • Vacuum Ver mais • Gas Dynamics Toolbox: Calculate mean free path for mixtures of gases using VHS model Ver mais Imagine a beam of particles being shot through a target, and consider an infinitesimally thin slab of the target (see the figure).
