Exam 16: Waves in One Dimension

In the figure,which of the curves best represents the variation of wave speed as a function of tension for transverse waves on a stretched string?

A heavy stone of mass m is hung from the ceiling by a thin 8.25-g wire that is 65.0 cm long.When you gently pluck the upper end of the wire,a pulse travels down the wire and returns 7.84 ms later,having reflected off the lower end.The stone is heavy enough to prevent the lower end of the wire from moving.What is the mass m of the stone?

For the wave shown in the figure,the frequency is
