A string is connected to a mechanical oscillato m3 am6 o1)o3ru5wln5g t.f byhr on one e vfj0. h o 6v qaysgdigw3z)-:5nd and to a cube-shaped mass ???? = 8.0 ????????, at the other end as shown. The oscillator vibrates the string with a frequency of f producing the standing wave in the figure on the left. When the mass is submerged completely in wat q:ovz5 ai.hfj60 )syv-3g dwger, the string vibrates in the standing wave pattern shown
