Homework Help: Waves in Aluminum

  1. Oct 5, 2011 #1
    1. The problem statement, all variables and given/known data
    Estimate the highest possible frequency (in Hertz), and the smallest possible wavelength, of a sound wave in aluminium, due to the discrete atomic
    structure of this material. We're given the mass of aluminum, Young's Modulus, and mass density.

    2. Relevant equations
    w=k* √(Y/ρ)

    3. The attempt at a solution

    Basically, I know that the largest wave has to fit inside the interatomic distance, but I don't know how to find this distance.
