    Graduate What does a high Debye temperature signify?

    What does a high Debye temperature mean? I know it's related to the phonon contribution to heat capacity at low temperatures, but that's about it. Specifically, why is the Debye temperature of copper so much higher than that of lead? (I'm working on this in lab right now and can't find an...

    Graduate Why can't a photon transfer all its energy to a free electron?

    Ok, I've got it. This explains it really well: http://74.125.95.132/search?q=cache:jrLlm5D0mPgJ:www.astro.indiana.edu/~classweb/a540_s05/notes/ch08.ppt+free+electron+can%27t+absorb+photon&cd=1&hl=en&ct=clnk&gl=us"

    Angle of particles after elastic collision

    Homework Statement A particle of mass M1 collides elastically with a particle of mass M2 at rest. Show that if M1>M2 then the angle of M1 after the collision cannot exceed the value arcsin(M2/M1). Homework Equations conservation of momentum: M1v1=M1v1`+M2v2` conservation of kinetic...

    Probabilities for system of two bosons

    Well, I guess if a=b=c, then they'd each have to be 1/sqrt3... unless we also have to take into account the 1/sqrt2 factor in front of |S>?

    Probabilities for system of two bosons

    If there are two indistinguishable bosons that can either be in the |0> or |1> state, what is the probability that both will be in the |0> state? (ie the system will be in the |0>|0> state) I know there are only three possibilities for the total state of the system: |0>|0>, |1>|1>, and...
