Question
![2) An A string on a violin is supposed to have a fundamental
frequency of 440 Hz. If the string is made of steel (0.00153
kg/m) and has a length of 32.5 cm, what is the beat frequency
if the tension is 720 N? What length of a pipe (open at one
end) would have a first harmonic of the same frequency?
Assume the speed of sound is 343 m/s](https://content.bartleby.com/qna-images/question/ee788985-6ee6-4669-9cb4-d143b6c80e7d/9d293428-b351-4bf1-924f-9e674673b867/haofti7_thumbnail.jpeg)
