Question

A tuning fork is tuned to vibrate at 440 Hz at a temperature of 20-deg C. How will the frequency of the sound produced change when the temperature decreases to 0-deg C? How will the wavelength change?

Answer #1

A tuning fork vibrating at 512 Hz falls from rest and
accelerates at 9.80 m/s2. How far below the point of release is the
tuning fork when waves of frequency 485 Hz reach the release point?
Take the speed of sound in air to be 340 m/s.ANS = 19.3 m

C" # has a frequency of 4,434.92 Hz in Equal Temperament Tuning.
In Just Intonation (tuned to A), the frequency of C" # is 4,400 Hz.
Find how many cents flatter the Just Intonation frequency of this
note is than the Equal Temperament Frequency of this note. Round to
the nearest cent.

A tuning fork of unknown frequency makes eight beats per second
with a standard fork of frequency 468.0
Hz.
The beat frequency decreases when a small piece of wax is put on a
prong of the fork of unknown frequency.
What is the frequency of this fork?

A tuning fork is supposed to generate an A5 note (880 Hz).
However, by some freak laboratory accident, a paperclip was
superglued to one tine of the tuning fork. Now when that tuning
fork is rung, there is a distinctive pattern of loudness and
quietness, that has been estimated to be around oscillations per
second. What is the new frequency of the affected tuning fork
tine?

You have three tuning forks, A, B, and C. Fork B has a frequency

Jennifer is using a tuning fork to tune her fifth guitar string,
which should be at a frequency of 110Hz, or note A2 in music terms.
When she rings the tuning fork and plucks her guitar string, she
hears 4.00beats/s.
(a) What are the two possible frequencies of Jennifer's guitar
string?
(b) When Jennifer loosens the string slightly, she hears
3.00beats/s. What is the frequency of the guitar string?
(c) Guitar strings have a fundamental harmonic with a wavelength
of...
