The discussion centers on the differences between the Einstein and Debye models of atomic vibration in solids, specifically addressing the frequency of vibrations among atoms in a crystal. Participants explore the implications of these models and seek to understand why atoms in the same type of crystal vibrate at different frequencies according to the Debye model.
Participants express differing levels of understanding regarding the Debye model and its implications, indicating that the discussion remains unresolved with multiple competing views on the topic.
Some participants express confusion about the specific questions being asked, suggesting that assumptions or definitions may not be fully clarified. The relationship between frequency and wavelength is noted to be linear only at low frequencies, indicating potential limitations in the discussion.
sirwan said:according to Einstein all atoms in solid vibrating with the same frequency , while in the Debye's mode there are a band of frequency i.e not all the atoms would have the same frequency, my question is that , that is the idea behind the Debye's model? or why the frequency of vibrating of atoms differ from one other in the same type of crystal.
