debye specific heat
Dear people,
I looked through the web and found a definition of debye secific heat and here is what it says:
The specific heat of a solid under the assumption that the energy of the lattice arises entirely from acoustic lattice vibration modes which all have the same sound velocity, and that frequencies are cut off at a maximum such that the temperature
of modes equals the numbers of degrees of freedom of the solid.
but i would like to know what the word "modes" and the word "degrees of freedom" means.
can anyone help me with this definition? :oops:
