| The '''Debye frequency''' of a [[crystal]] is a theoretical maximum [[frequency]] of [[oscillation|vibration]] for the [[atom]]s that make up the crystal [http://scienceworld.wolfram.com/physics/DebyeFrequency.html]. It was proposed by [[Peter Debye]] as part of the '''[[Debye model]]'''. It is generally not the same as the actual maximum oscillation frequency for the crystal, due to approximations in the model, however it is still a useful quantity [http://farside.ph.utexas.edu/teaching/sm1/lectures/node71.html].

The writer is known by the title of Figures Lint. Managing individuals is his occupation. Minnesota has always been his house but his wife wants them to transfer. One of the extremely very best issues in the globe for me is to do aerobics and now I'm trying to earn money with it.
