8/07 2 Equipment: signal generator, string vibrator, set of weights, meter stick, digital balance, pulley, desk clamp, string (white/green, white/red, etc.), leads Theory: A fundamental equation of wave motion is f v λ = (equation 1) where v = velocity, f = frequency and = wavelength of the wave. The velocity of a transverse wave traveling along a string is given by the equation μ T v = (equation 2) where T is the tension in the string and is the mass per unit length of the string. If one end of the string is held fixed (on a pulley) and the other end is attached to a vibrator so that its direction of vibration is perpendicular to the string. Proper adjustment of the string’s frequency of vibration can produce stationary waves on the string, yielding an integral number of half wavelengths on the string. The distance between adjacent nodes is 2 . Note that the harmonic number corresponds to the number of anti-nodes . Procedure:
