I have three questions relating to wave physics

  1. Sep 12, 2010 #1
    A piano tuner detects that the "middle C" note, which should be 261.6 Hz, is too low by 11.7 Hz. If the original tension was 744 N, what must it be adjsuted to so the note plays the correct frequency?

    A wave on a large cable, of mass per unit length 1.52 kg/m, is generated by a machine providing 201 W of power. It produces waves of wavelength 2.23 m and amplitude 1.52 m. What is the speed of these waves?

    A string is made of two materials of different mass per unit length, 2.33 g/m on the left and 3.31 g/m on the right, connected together at the center. If the wavelength of the wave on the left segment is 22.4 m, what is the wavelength on the right?
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
