Caroline, a piano tuner, suspects that a piano's A4 key is out of tune. Normally, she would play the key along with her A4 tuning fork and tune the piano to match, but her A4 tuning fork is missing. Instead, she plays the errant key along with her G4 tuning fork (which has a frequency of 392.0 Hz), displays the resulting waveform on a handheld oscilloscope, and measures a beat frequency of 86.4 Hz. Then, she plays the errant key...

While attempting to tune the note C at 131 Hz, a piano tuner hears 5.00 beats/s between a reference oscillator and the string. (a) What are the possible frequencies of the string? (Give the frequencies to the nearest integer.) lower possible frequency Hz higher possible frequency Hz (b) When she tightens the string slightly, she hears 6.00 beats/s. What is the frequency of the string now? (Give the frequency to the nearest integer.) Hz (c) By what percentage should the...

5) A 67 cm guitar string (density = 0.8 g/cm) is out of tune. The ambient temperature is 20 C. When tuning the guitar string against a 440 Hz tuning fork, the guitarist hears a beat frequency of 4 Hz. By tightening the string, it is tuned to A at 440 Hz. a) What was the frequency of the untuned string? b) How much did string tension change when tuning this string to 440 Hz?

A piano tuner sounds two strings simultaneously. One has been previously tuned to vibrate at 293.0 ??. The tuner hears 3.0 beats per second. The tuner increases the tension on the as-yet untuned string, and now when they are played together the beat frequency is 1.0 beat per second. (a) What was the original frequency of the untuned string? (b) What is the frequency of the unturned string corresponding to 1.0 beat per second? (c) By what percentage did the...
