What's the linear mass density of a string?

If the string vibrates in its third harmonic ...?

  • Two waves traveling in opposite directions along a string fixed at both ends create a standing wave described by y(x,t) = 0.01 sin (24.9x) cos (1150t). The string has a linear mass density of 0.0115 kg/m, and the tension in the string is supplied by a mass hanging from one end. If the string vibrates in its third harmonic ... a) ... calculate the length of the string. b) ... calculate the velocity of the waves. c) ... calculate the mass of the hanging mass.

  • Answer:

    I was an A string at 440Hz
