Homework Help: Tranverse waves and velocity problem

  1. Nov 16, 2006 #1
    A piano string of length 1.6 m and mass density 26 mg/m vibrates at a (fundamental) frequency of 450 Hz.

    (a) What is the speed of the transverse string waves?
    (b) What is the tension?
    c) What are the wavelength and frequency of the sound wave in air produced by vibration of the string? The speed of sound in air at room temperature is 340 m/s.

    I have been working on this problem and cannot seem to come up with the solution. Any help would be greatly appreciated.

    What have you done so far?

    What's the wavelength of the fundamental mode? How are speed, wavelength, and frequency related?

    What's the relationship between tension, mass density, and wave speed?
