Question

Actually one question that has multiple parts to the question. 

A guitar string with mass density p = 2.4 x 104 kg/m is L= 0.98 m long on the guitar. The string is tuned by adjusting the
tension to T = 100.4 N.
1) With what speed do waves on the string travel?
m/s Submit
2) What is the fundamental frequency for this string?
Hz Submit
3) Someone places a finger a distance 0.155 m from the top end of the guitar.
What is the fundamental frequency in this case?
Hz Submit
4) To "down tune" the guitar (so everything plays at a lower frequency) how should the tension be adjusted?
increase the tension
O decrease the tension
Ochanging the tension will only alter the velocity not the frequency
