In the arrangement shown below, (screenshot attached) an object can be hung from a string (with linear mass density

μ = 0.00200 kg/m)

that passes over a light pulley. The string is connected to a vibrator (of constant frequency f), and the length of the string between point P and the pulley is

L = 1.60 m.

When the mass m of the object is either 9.0 kg or 16.0 kg, standing waves are observed; no standing waves are observed with any mass between these values, however.

 

(a)What is the frequency of the vibrator (in Hz)?

(b)What is the largest object mass (in kg) for which standing waves could be observed? 

(c) What would the linear mass density of the string have to be (in kg/m) if 16.0 kg is the largest mass for which standing waves are observed?  

(d) For what values of m (in kg) would standing waves with the next four higher numbers of nodes be observed in this case? (m1 =?, m2=, m3=, m4=, m5=)
