I need help getting started solving the following.
Show that when the recoil kinetic energy of the atom, p^2/2M, is taken into account the frequency of a photon emitted in a transition between two atomic levels of energy difference delta-E is reduced by a factor which is approximately (1 -...
OK, I have this homework problem that I need some help solving . The question is as follows:
Consider two events that take place at different points in the K system at the same instant t. If these two points are separated by a distance delta-x, show that the events are not simultaneous in...
