Phonon dispersion relation for ID monatomic chain was derived in our lecture note in the module for "Gas Kinetics and Phonons'. Now, generalize the treatment of a monatomic linear chain to the transvers vibrations of atoms on a 2D square lattice of atoms and show that 1/2 - (2K) ¹7² [2 - cos q₂a - m @= sqya] ¹/2 COS Phonon dispersion relation for ID monatomic chain was derived in our lecture note in the module for "Gas Kinetics and Phonons'.
