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?
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
I'm not sure if my method is right, so please check that! thanks
2. Not sure about this one
Thanks for the help
