Simple harmonics - sound waves

  1. Sep 14, 2008 #1
    1. The problem statement, all variables and given/known data
    A 2.40 kHz sound wave is transmitted through an aluminum rod.

    A) What is its wavelength in the aluminum?
    B What is the sound wave's frequency when it passes into the air?
    C) What is its wavelength in air?

    The speed of sound in aluminum is 5100 m/s according to the book.
    2. Relevant equations


    3. The attempt at a solution

    So...This is what I was doing, which apparently is wrong.


    frequency=2.4 * 10^3 Hz
    Velocity = 5100 meters/sec

    5100m/s=(2.4 * 10^3)hz *lambda


    But apparently that isn't the answer for part A...So I must have done something wrong somewhere...

    So...thank you in advance for any help.
