(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1. An unfingered guitar string is 0.70 m long and is tuned to play E above middle C (330 Hz). How far from the end of this string must the finger be placed to play A above middle C (440 Hz)?

2. An organ is in tune at 20 degrees C. By what fraction will the frequency be off at 0 degrees C?

2. Relevant equations

3. The attempt at a solution

1. I used the v=(freq)(wavelength) equation:

v = (330)(0.70) = 231 m/s

Then i plugged in 231 to figure out the distance for 440 Hz:

(231 m/s) = (440)x

x=.525 m

I'm not sure if my method is right, so please check that! thanks

2. Not sure about this one

Thanks for the help
