(adsbygoogle = window.adsbygoogle || []).push({}); 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

Velocity=frequency*lambda

3. The attempt at a solution

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

Velocity=frequency*lambda

frequency=2.4 * 10^3 Hz

Velocity = 5100 meters/sec

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

lambda=2.125m

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.
