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 0.620 g/m and the tension is 160 N, how long is the vibrating section of the violin string?
T = 160N
Linear Density = 0.62g/m
Wavelength of violin string = 0.391m
Speed of sound in warm room = 344m/s
m = 1?
Homework Equations
v = [tex]\sqrt{\frac{T}{\mu}}[/tex]
v = [tex]\lambda[/tex][tex]\times[/tex]f
The Attempt at a Solution
I all know is to find the velocity of the string first which is the square root of 250 or about 15.811m/s. I am unsure of what to do next. Also, what is the "vibrating section of the violin string"? I am unsure of what that is. Thanks in advanced.
