Calculate Highest Freq. & Smallest Wave in Aluminium

In summary, the highest possible frequency of a sound wave in aluminum is related to Young's Modulus, mass density, and spring constant, with the equation w=k*√(Y/ρ). The smallest possible wavelength is determined by the interatomic distance, but the method for finding this distance is unclear.

Homework Statement


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.



Homework Equations


w=k* √(Y/ρ)



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.
