The beats are the sum and difference of the components ... (A + B) and (A - B).
If something really non-linear is also going on, you also get (2A - B), but we'll
leave that alone for right now.
That pair of forks produces beats at 2 Hz and 990Hz .
Number of beats heard in one second will be got by the difference between the parent frequencies. Hope you have given wrong data for parent frequencies. The first one has to be 220 Hz and the other is 226 Hz. Hence 6 beats will be heard in one second.
If you say 20 is the right one then difference will be 206. If 206 beats get produced in one second it will not be named as beat at all. Moreover our hearing could not recognize this as beating at all. So better correct the given data.
a tuning fork is made by.....use of a specific frequency..................

Tuning forks are available for all standard notes, but the most common is an A note, which is 440 Hz
if u hit it on a wooden desk (like a classroom desk) it will vibrate and you can see and feel the vibration of a tuning fork like that. If u touch it ur finger/hands will keep it from vibrating .

Put it by something which will resonate in sympathy with it, such as a soundbox or sympathetic string.
If electricity is an option, electrical amplification can make a sound as loud as needed.
The low-pitched tuning fork (C128) is used to test sensation of vibration. Higher pitched tuning forks are used in neurological examinations.
Usually it's the principal oboe. In case of a piano concerto, the orchestra will tune to the piano.
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
340 hz is the pitch or note that is sounding. It's the times the string would vibrate per second. By 350 hz guitar, I would get you would be playing a note on the low E string and it would sound sharp to the tuning fork. You would hear a subtle beat or pulsing when sounded together. That beat would get slower and slower as you loosened the string to bring the pitch down until it quit altogether. Your would then have that note tuned to 340 hz. BTW...standard tuning is called A440 meaning that the A note is tuned to 440hz.
Yes.
It's an effect called 'resonance' - two identical things can vibrate in synch if the vibrations of one can someone pass to the other. The usually way of doing this is to stand them both on the same surface, so that the vibration can pass through that object.
20Hz and 270Hz
Most tuning forks are designed to resonate at 440 hertz when struck. That is the frequency of the A before middle C on a keyboard or the A string on a guitar, violin, etc. You just strike the tuning fork then adjust the tension on your A string until the string vibrates at the same frequency as the tuning fork. Then you tune the rest of your strings from the A string.
it will fizz because the vibration will shake the water and create a motor effect
a wooden surface is better for a tuning fork rather than, say, a metal surface because the wood vibrates less than metal, and doesn't interfere with the vibrations of the fork. rubber is probably the best surface to hit a fork on.
Tune the piano's A440 to the fork. You don't have to tune it perfectly at first. As long as you know what side of "smooth" you're on, you can tune A440 so that there is a comfortable beat-rate when played with the fork. Then tune the piano's A220 to the piano's A440. Make the beat rate for A220 the same as when you play A440 against the fork. If you made A440 sharp, tune A220 "outside of smooth". If you made A440 flat, tune A220 "inside of smooth". A220 will be in tune. Alternative: Tune one wire of A3 with the fork, as described above (but tune it near the correct frequency). Then tune the other wires of A3 to the first one, using the same "beat" idea. Finish by pulling the first wire to unison.
The effect of temperature on the frequency of a tuning fork is slight, for the length of the tines is little changed. A steel tuning fork would not be used as a precision frequency reference, though quite adequate for audio purposes.
As the temperature increases, the lines will lengthen, and the frequency will decrease.
Although the tuning fork is not usually thought of as a musical instrument, technically, it would be classified as a percussion instrument.
