The second harmonic of a guitar string has a frequency of 120 hz. what is the length of the guitar string if the speed of the waves on the string is 110 m/s?

L = 0.917 m

Explanation:

For nth harmonic of the frequency of the Guitar we can say

here we know

n = nth harmonics

v = speed of sound in the string of guitar

L = length of the guitar

now from this equation we have

given that

f = 120 Hz

so we have

show the wavelengths of a wave. show the crests of a wave.
