Jennifer is using a tuning fork to tune her fifth guitar string, which should be at a frequency of 110 Hz, or note A2 in music terms. When she rings the tuning fork and plucks her guitar string, she hears 8 beats/s. Note: parts (a) and (b) require absolute accuracy. Your answer must be exactly correct-not just within 5% (a) What are the two possible frequencies of Jennifer's guitar string? fmAx Number Units Number Units min (b) When Jennifer loosens...
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 violinist tuning a string on her instrument to a tuning fork of 440 Hz detects 4 beats per second. When she loosens the string (which de- creases the frequency of the sound produced by the string), the number of beats per second initially goes down, but as she continues to loosen the string, the number of beats per second starts to increase. The fre- quency of the sound produced by the string on her violin before she started loosening...
A guitar string produces 7 beats/s when sounded with a 350-Hz tuning fork and 2 beats/s when sounded with a 355-Hz tuning fork. What is the vibrational frequency of the string?
A piano tuner uses a tuning fork to tune a string to 140??140Hz . When the tension is 610?610N , he hears a beat frequency of 1.9??1.9Hz . The beat frequency decreases if the tension is increased. What is the correct tension?
We want to tune the second string of a guitar to its standard frequency of 245 Hz. We listen to the beats produced when the string is played at the same time as a tuning fork. (a) If we hear 6 beats/s, should the tension in the string be increased or decreased? Explain. (b) We decrease the tension and the beating increases to 10 beats/s. Should we tighten or loosen the string? (c) Starting from 10 beats/s, by what percentage...
A tuning fork vibrates at a frequency of 530 Hz. An out-of-tune piano string vibrates at 535 Hz. How much time separates successive beats?
When a guitar string is sounded along with a 430 Hz tuning fork, a beat frequency of 4.00 Hz is heard. When the same string is sounded along with a 425 Hz tuning fork, the beat frequency is 9.00 Hz. What is the frequency of the string?
The G-string on a guitar is 64.8 cm long and is properly tuned to 196 Hz (fundamental) frequency. Sketch the first harmonic on this guitar string at two different times. What is the frequency of the G note one octave above this frequency? One octave below? What is the frequency of the note a perfect fifth above this frequency? What is the wavelength of the first harmonic of this guitar string? What is the speed of waves on this guitar...
A flute player hears four beats per second when she compares her note to a 523 Hz tuning fork (the note C). She can match the frequency of the tuning fork by pulling out the "tuning joint" to lengthen her flute slightly. What was her initial frequency?
