Spring mass model

[yellowgold]

What is the spring mass model ? If we know atomic mass how we can determine spring constant? Is there any equation ?

I have no idea what you are talking about, are you talking about phonons in solids?

[yellowgold]

Yes I mean phonon in Solid...

[malawi_glenn]

you measure the speed of sound, that is one way to do it.

The best you can do is to google or go to the library and get yourself a textbook.

Wikipedia also have a formula, it depends on what kind of model you are using.

Why are you asking this question? Is it a course in solid state physics you have now or what?

[yellowgold]

yes . there is a course about nanoscale energy transport. photon phonon electron. And I dont have any background about quantum. So I try to get info about some consepts.

[malawi_glenn]

ok you don't need any quantum physics to get the spring-model of phonons in solids.

Best way to get the concepts is perhaps to pick up a textbook, try to ask the teacher if he knows any good one which you can borrow or recomend in the library.

I personally are trained with Kittel, which is a terrible textbook! I had a really great teacher altough.

But you know some physics of waves etc? Dispersion relation and speed of wave?
