Physics guitar string frequency problem?
A guitar string is tuned so that it produces a fundamental frequency of 440 Hz. If the length of the string is 0.60 m how far from the end of guitar string would you need to hold it down to produce a frequency of 480 Hz?
Charles your answer was near correct. I was able to figure it out. The last step was to subtract .55m from the length of the string (.6m)
so,
.6 - .55 = .05m
thank you!

Hey Dave,
The equation for frequency of a vibrating string is as follows,
f = v / 2L
where v is the speed at which the waves are moving on the guitar
and L is the length of the string which is .6m in our case
plugging everything in and solving for v,
v = 2Lf = 2(.6m)(440Hz) = 528 m/s
now, solving for L'
L' = v / 2f' = 528 m/s / 2*480Hz = 0.55m
Hope this helps, check out the wiki article too if you need some more info.
