These formulae deal with the Debye model in any respect temperatures. The more elementary formulae supplied additional down provide the asymptotic actions within the limit of reduced and high temperatures. The Slice-off frequency can be determined through the Slash-off wavelength. From your sampling theorem, we are aware that for wavelengths https://www.facebook.com/permalink.php?story_fbid=pfbid0jqi3NgugHLMYqkHg6yMNLijt4NhP9ymizBXrmghMKQArLtFHkUQxmZ8gigvToacwl&id=61560512640678&__cft__[0]=AZV9cuKUhWNmuM4td6uaCNMKn8pkv5lcLlKIhudN-DxakRgvWsf_rBsav4dRBXSNrlpScphBEJju6srd5IhHfMeKffXrYyF_D7L08TIM_rW5XKPLXj8ayKzvNkRzef4zyKBBDBLR1fvOmASdcI8RtNw7p-BsFewmWGI8PGlk2M4VcT-pAfjZ3fcm8_AazFwK2xquLzpmQE2Hs_g1jnqwqfTf&__tn__=%2CO%2CP-R
