we are given a simple one-dimensional crystal consists of a chain of atoms of mass M with an equilibrium spacing a. It is assumed that the atoms only move in the direction parallel to the chain, and that the atomic motions can be modelled as identical to those of a chain of identical masses M connected by identical springs of spring constant K. The velocity of sound in the crystal is 253 ms-1. If the equilibrium spacing is 4 Å and the spring constant is 0.02 Nm-?, what is the mass (in AMU ) of the atoms?
