How does the velocity of sound depend on the temperarure.(adsbygoogle = window.adsbygoogle || []).push({});

If you set up a simple model of a linear lattice with nearest neighbour

interaction only you get the dispersion relation:

w^2=4c/M * sin^2 (0.5ka)

and v=w/k.

where a is the spacing between atoms, c is the force constant, k the wavevector and M the mass of an atom.

Of these only c dependes on temperature?

How do you model, explain, show how c dependes on temperature?

Maybe you know a better way to show how sound velocity dependes on

temperature.

Thank you.
