A piano tuner detects 3 beats per second when she is tuning a string to a tuning fork of frequency 440 Hz. When she tightens the string, which increases the frequency of the string, the frequency of the beats initially goes down, and as she keeps increasing the frequency of the string, the frequency of the beats starts to increase. What was the original frequency of the string?

a. either 437 Hz or 443 Hz (One cannot tell without more information.)

b. 443 Hz

c. 440 Hz

d. 437 Hz

The heart rate of a fetus, in beats per second (bps), is an indicator of baby gender. To determine the gender of his kid, Resh decide to buy an at-home heart monitor. For the next 30 days, Resh measures the heart rate of the fetus. The average heart rate measured over the past 30 days is 129.5 bps. Previous research established that the population’s standard deviations is 20 bps. Also, the previous research suggest that fetal heart rate is normally...

A standard violin string is 32.8 cm long from the tuning peg to the bridge. When played open(without pressing a finger against the fingerboard), this string has a fundamental (lowest)frequency of 440 Hz. (a) What is the wavelength of the wave at this frequency? (Hint: the lowest frequency is alsothe longest wavelength that can produce a standing wave.) b. (b) What is the speed of the wave on the string? (Hint: this is not the speed of sound!)c. (c) How...

A musician in a concert hall is tuning her wind instrument. When she plays a short note she hears the echo of the note return from the opposite side of the 50.0 meter long auditorium 0.294 seconds later. Model the instrument as a tube closed at one end, if the instrument is properly tuned the note of the musician played would have a frequency of 233.082 Hz, but instead has a frequency of 226.513 Hz. This note is the first...
