Question

The speed of a transverse wave on a stretched string can be changed by adjusting the tension of
the string. A stationary wave pattern is set up on a stretched string using an oscillator set at a
frequency of 650 Hz.


How must the wave be changed to maintain the same stationary wave pattern if the applied
frequency is increased to 750 Hz?

How must the wave be changed? Do you meant tension be changed?

f=sqrt(tension)

750/650 = sqrt(T)

T=1.331 so the tension must be increased 33 percent.
