Homework Statement
A particularly beautiful note reaching your ear from a rare Stradivarius violin has a wavelength of 39.1 cm. The room is slightly warm, so the speed of sound is 344 m/s.
If the string's linear density is 0.560g/m and the tension is 160N , how long is the vibrating section of the violin string?
Homework Equations
f=c/wavelength
f=sqrt(F/(m/L))/(2L)
The Attempt at a Solution
frequency = (344m/s) /(.391m) = 879Hz
879=sqrt(160/(.000560/L))/(2L)
i converted .560g/m to .000560kg/m because force is in Newtons
did algebra and got that length is 10.81m, which is wrong.
Not sure what I did wrong though.
