Homework Statement
A violin string with a mass of 0.35g is 33 cm long. The frequency of a wave supported by the string is 196 Hz.
What is the speed of the wave?
Homework Equations
Ln = n/2 *lambda
v = f*lambda
The Attempt at a Solution
1. Solve for wave length [/B]
L1 = 1/2 *lambda
0.33 = 1/2 * lambda
0.33 *2 = lambda
0.66 = lambda
2. Solve for speed of wave
v = f * lambda
v = 196 * 0.66
v = 129.36 m/s
I just assumed you have to use first harmonic and got the right answer, but why do we have to use first harmonic? or is there another way to do it?
