Photon energy meaning
Did you know?
WebThe energy fluence Y describes the energy flow in a photon beam and is defined as the amount of energy dE crossing a unit area dA: (6.3) The unit of energy fluence Y is MeV/cm2. For a monoenergetic beam, dE is the number of photons dN times their energy hn, and the energy fluence Y in terms of photon fluence f is: Y = fhn (6.4) WebDefinition. An electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. Hence, it has a value of one volt, 1 J/C, multiplied by the elementary charge e = 1.602 176 634 × 10 −19 C. Therefore, one electronvolt is equal to 1.602 176 634 × 10 −19 J. ...
