3. A cello and an organ are playing together. The organ plays a pitch of C with a frequency of 65.4 Hz in a pipe open at both ends. The cello plays its C string (a string fixed at both ends), and a beat frequency of 2.5 Hz is heard. The cellist loosens the string until no beat frequency is heard. a. What was the initial frequency played on the string? b. Now the cello is playing a note of frequency 65.4 Hz. The string has a linear density of 15.6 g/m and a length of 70 cm. What is the tension in the string? c. What is the length of the pipe?
