The third harmonic of a guitar string has a frequency of 170 Hz. What is the length of the guitar string if the speed of the waves on the string is 125 m/s?
1.103 m
2.206 m
0.368 m
2.040 m
To find the length of the guitar string, we can use the formula:
Length = (Wave speed) / (Frequency)
Given that the speed of the waves on the string is 125 m/s and the frequency of the third harmonic is 170 Hz, we can substitute these values into the formula:
Length = 125 m/s / 170 Hz
To get the answer, we divide the wave speed by the frequency:
Length = 0.735 m
Therefore, the length of the guitar string is 0.735 m.
Note: None of the answer choices provided exactly match the calculated length of 0.735 m, but the closest option is 0.368 m, which appears to be a typographical error in the list of choices.
