Incoming photon
WebThis result is for the cross section averaged over all incoming photon polar-izations. By integrating Eq. (7) over all angles, the total cross section can be obtained. While the expression for the total cross section is a lengthy formula, two asymptotic expressions for the total cross section σ c in the low energy and high energy case are more ... WebEinstein also argued that the light intensity did not depend on the amplitude of the incoming wave, but instead corresponded to the number of photons striking the surface within a given time period. ... the kinetic energy of an ejected electron will increase linearly with the energy of the incoming photon. Example 6.2. Calculating the Energy of ...
