A 0.4 guitar string is vibrating in its fundamental frequency. The maximum acceleration of a point at the middle of the string is 8400m/s^2 amd the maximum velocity of that point is 3.80m/s.
What is the amplitude of the wave?
What is the wave speed?
The fundamental frequency for the string is in resonance with the fundamental frequency of tube that is open at one end. Find the length of the tube
