Beats are interference patterns between two sounds of slightly different frequencies. In this Demonstration, beats are produced by sound waves emitted by two tuning forks. You can vary the frequencies and listen to the sound waves.
The pitch that a particular tuning fork generates depends on the length of its prongs. Each fork is stamped with the note it produces (e.g. A) and its frequency in Hertz (e.g. 440 Hz). Shorter prongs produce higher pitch (frequency) sounds than longer prongs.
Tuning forks are available in a wide range of frequencies (64 Hz to 4096 Hz); 128 Hz is a commonly used frequency for screening.
What happens when you put two tuning forks together?
Striking one tuning fork will cause the other to resonate at the same frequency. When a weight is attached to one tuning fork, they are no longer identical. Thus, one will not cause the other to resonate. When two different tuning forks are struck at the same time, the interference of their pitches produces beats.
What affects the frequency of A tuning fork?
The pitch that a particular tuning fork generates depends on the length of its prongs. Each fork is stamped with the note it produces (e.g. A) and its frequency in Hertz (e.g. 440 Hz). Shorter prongs produce higher pitch (frequency) sounds than longer prongs.
Do tuning forks have different frequencies?
Tuning forks are available in a wide range of frequencies (64 Hz to 4096 Hz); 128 Hz is a commonly used frequency for screening.
Why do shorter tuning forks have higher frequency?
Shorter tuning fork creates a higher pitch, not as loud, so high frequency waves with low amplitude. The longer tine tuning fork is able to move back and forth over a longer distance and displace more air molecules, resulting in longer wavelengths with higher amplitude.
What happens when you hit two tuning forks together?
If a tine on one of two identical tuning forks is wrapped with a rubber band, then that tuning forks frequency will be lowered. If both tuning forks are vibrated together, then they produce sounds with slightly different frequencies. These sounds will interfere to produce detectable beats.
What will happen if A vibrating tuning fork is placed near another at the same frequency?
What will happen is a vibrating tuning fork is placed near another tuning fork of the same frequency? A sympathetic vibration will occur which means that the sound waves will travel through the air and make the other tuning fork vibrate.
What are two things tuning forks are used for?
Tuning forks, typically aluminum, consist of a stem (handle) and two prongs that form a U-shaped fork (Figure 4-13). The tuning fork vibrates at a set frequency after being struck on the heel of the hand and is used to assess vibratory sensation and hearing (air conduction and bone conduction).
Does tuning fork increase frequency?
When the fork as heated it expanded causing the length of the tines to increase. This increase in length caused the frequency to be lower because the length of the tines depicts the frequency (wavelength) of the fork. The longer tuning forks have lower frequency while the smaller ones have a high frequency.
Which factors depends on the frequency of tuning fork?
Answer: the frequency (n) of a tuning fork depends upon the length (L) of its prongs, the density (d) and Young’s modulus (Y) of its material. It is given as nu221dL ad bYc.
Does frequency of tuning fork depends upon mass?
A tuning fork’s pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments.
How do you change the frequency of A tuning fork?
If the two tuning forks to be producing a “beat” frequency of 8 beats a second, then then difference between the two would be 8 Hz. So as you know one of them is 288 Hz. You just need to add or subtract 8 from that to get there other tuning forks possible frequency so it is 280Hz (288Hz-8Hz) or 296Hz (288Hz+8Hz).
How does increasing the length of the tuning fork affect frequency?
This increase in length caused the frequency to be lower because the length of the tines depicts the frequency (wavelength) of the fork. The longer tuning forks have lower frequency while the smaller ones have a high frequency. The frequency of the tuning forks is inversely relative opt the length of the tines squared.
Are all tuning forks the same?
A tuning fork’s pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments.
What is the difference of frequencies of two tuning forks?
Explanation: Number of beats produced in one second is equal to the difference between the frequencies of the two tuning forks.
Why do different tuning forks have different sounds?
The tone a fork makes is determined primarily by the length of its “tines” (or prongs). Longer tines vibrate more slowly and thus produce a lower tone. Shortening the length of the tines allows them to vibrate faster and thus produce a higher sound.
What is the difference between different tuning forks?
With unweighted tuning forks, the difference lies in the intensity of the vibration. Unweighted tuning forks are used more for hearing evaluation as they do not provide the same frequency as weighted tuning forks. As mentioned earlier, the heavier the fork weight is, the more powerful its vibration.
More Answers On Could Another Tuning Fork With A Frequency Lower
Beat frequency with tuning forks – Physics Stack Exchange
What is the frequency of the second tuning fork? The answer is 311 Hz. But I don’t understand how we can arrive there. The two things we know are $1.$ that the new frequency is $>$ 305 Hz and $2.$ that the beat frequency decreases from 6 Hz to 4 Hz. How does this then tie together that the other frequency is definitely 311 Hz?
Frequency of Tuning Fork – Physics Stack Exchange
If the tines of a tuning fork are struck very hard the frequency will be lower because the tines have farther to move and; though the internal restoring force also increases with displacement, it will not be enough to exactly keep the frequency steady. Thus cheap soft metal oscillating things go “boing” or “twang”.
How can we change a tuning fork frequency? – Quora
If you look into this formula,increasing mass without adding much stiffness results in lower frequency. When waxed, we add the mass of wax to the tuning fork, but this was hardly increases the stiffness of the fork. Thus the denominator rises more than numerator and hence results in a lower frequency. 5K views View upvotes Related Answer
Tuning fork – Wikipedia
A change in frequency of 48 parts per million per °F (86 ppm per °C) is typical for a steel tuning fork. The frequency decreases (becomes flat) with increasing temperature. Tuning forks are manufactured to have their correct pitch at a standard temperature. The standard temperature is now 20 °C (68 °F), but 15 °C (59 °F) is an older standard.

How Tuning Forks Work – HowStuffWorks
The faster a tuning fork’s frequency, the higher the pitch of the note it plays. For instance, for a tuning fork to mimic the top key on a piano, it needs to vibrate at 4,000 Hz. To mimic the lowest key, on the other hand, it would only need to vibrate at 28 Hz. But how do you adjust the speed at which a tuning fork vibrates?
How do tuning forks stay in tune, and can they ever go out of tune?
What happens when the prongs of a tuning fork are made thinner? All things being equal, reducing the mass will raise the frequency. Generally, the larger the tuning fork the lower the pitch, the smaller the higher. Large things move slower and so will vibrate at a lower frequency, small things are lighter and so will vibrate at a higher frequency.
electromagnetic tuning fork use – Red Wave Radio
The tuning fork was packaged in an aluminum can and included a pair of driver and pickup electromagnets attacked to the rectangular fork.

Why does a tuning fork have a fixed frequency? – Quora
If the two tuning forks to be producing a “beat” frequency of 8 beats a second, then then difference between the two would be 8 Hz. So as you know one of them is 288 Hz.

Vibrational Modes of a Tuning Fork – Pennsylvania State University
In addition to the in-plane bending modes, a tuning fork will also exhibit several out-of-plane bending modes where the fork acts like a solid bar, vibrating perpendicularly to the plane of the tines. Frequencies (left to right): 457 Hz, 2861 Hz. The lowest of these modes is very close to the fundamental frequency.

harmonics – Why don’t tuning forks produce overtones? – Music: Practice …
The tuning fork does produce overtones. The amount of overtone depends on how the tuning fork is attacked. The modes of attack also depend on the pitch of the fork.
