Question

A string of a violin that has a length 0.8 m is pulled with a force that produces a fundamental vibration of 190 Hz. What speed do the transverse waves have on this violin string?

Answer 1

We can find the speed of the transverse waves from the formula for the fundamental frequency:
f_1=v/2L,
here, v is the speed of the transverse waves, L is the length of the string.
Then, we get:
v=2Lf_1=2∙0.8 m∙190 Hz=304 m/s.
