1. ### KE = p^2/(2m)

refer to the title. I'm confused whether this eqn works in relativistic situations? thanks in advance
2. ### Quantum mechanics

bump :confused:
3. ### Quantum mechanics

I stated the problem as it is given in the book
4. ### Quantum mechanics

Charges of +q and -q are separated by a distance L. What would be a typical energy of a virtual photon they exchange?
5. ### Another quantum mechanics question

The equations for R and T in the E > U0 barrier are essentially the same as for light passing through a transparent film. It is possible to fabricate a thin film that reflects no light? Is it possible to fabricate one that transmits no light? Why or why not?
6. ### Quantum mechanics

Let me type the exact q ... A beam of particles of energy E and incident upon a potential step of U0 = 3/4 E is described bby the wae funciton Y(x) = 1 e^(ikx) The amplitude of the wave (related to the number incident per unit distance) is arbitrarily chosen as unity. a) Determine...
7. ### Quantum mechanics

if you know the wave ... how do you determine the reflected and transmitted waves? the book tells you to enforce the required continuity conditions to obtain their (possibly complex) amplitudes
