A violinist places her finger so that the vibrating section of a 1.0g/m string has a length of 30cm, then she draws her bow across it. A listener nearby in a 20 degrees celcius room (speed of sound at this temperature in air is 343 m/s) hears a note with a wavelength of 40 cm. What is the tension in the string?
I was having real trouble with this question.
How are we meant to use the frequency of the wave in the air and transpose that information back into the string if we have no way of knowing the frequency/wavelength changes when the string hits the discontinuity of the medium (string-air)?
