The "middle C" note of a piano, which has a fundamental frequency of 256 Hz, is generated when a "hammer" inside the piano strikes a string with a length of 0.77 m (a) Assuming the tension is the same in all of the strings in the piano, what is the length of the string that produces the "A above middle C" tone with a fundamental frequency of 440 HZ? La= Number Units (b) What are the frequencies of the first three overtones on the "A above middle C string? List them in ascending order
