## Homework Statement

A string from an Andrew Kirk violin is 30.0 cm long, with a linear density of 0.645 g/m. The violin is placed near a loudspeaker that is fed by an audio oscillator of variable frequency. It is found that the string is set into oscillation only at the frequencies 1312 Hz and 1749 Hz, as the frequency of the oscillator is varied over the range 1093 Hz to 1968 Hz. What is the tension in the string?

## Homework Equations

v=sqrt(T/linear density) v=lambda x frequency

## The Attempt at a Solution

I made these 2 equations equal to each other. However, I am unsure as to what proportion of L lambda is, and what to use for frequency. Once I know what to do here I can then isolate for tension and solve.

Thanks in advance, any help would be GREATLY appreciated.
