Question #38247
In analyzing the motion of an elastic wave through a material medium,we often ignore the molecular structur of matter.when is this justified and when is it not?
plzzz anx me ryt now.........
Expert's answer
Everything is dependent on the ratio between wavelength L and crystal lattice constant a: if L much greater than distance between neighboring atoms of medium, we can ignore molecular structure of matter. But if wavelength is small (wave vector k is large) then we need to consider discrete structure of crystal lattice.
