The frequency of an elastic wave passing through a one dimensional monatomic lattice is given by co(q) = a, sin (22), where a is the lattice spacing and q is the wave number and is a material-specific constant. How does , depend on atomic mass? Calculate the velocity of the wave when the wavelength becomes much greater than the lattice spacing. Explain how a lattice could be used as a mechanical frequency filter. 106 The frequency of an elastic wave passing through a one dimensional monatomic lattice is given by co(q) = a, sin (22), where a is the lattice spacing and q is the wave number and is a material-specific constant.
