tuning fork steel instrument in the shape of a U with a short handle. When struck it produces an almost pure tone, retaining its pitch over a long period of time; thus it is a valuable aid in tuning musical instruments.
Frequency(f)= number of turns(1) "we use one (1) as default to stand for one full cycle and can be used for vibrations" divided by time(t). therefore f=1/t, frequency is measured in hertz. in the question 1=1500 vibrations and t=3 seconds. using this: f=1500/3 = 500 hertz
You would be using a radio if you were trying to tune into an AM or FM frequency.
The pitch usually refers to the note produced so the pitch will vary on which tuning is being used. Easier to explain by example: Most uke players use either the GCEA or the ADF#B tuning those using the ADF#B tuning will produce the same tune as the one using the other - whilst using exactly the same fingering, but it will be pitched a full tone higher.

For every frequency there is an antenna that is perfect for radiating at that frequency. Unfortunately, it would be unrealistic to carry a separate antenna for every frequency that a communications center is capable of radiating. To overcome this problem, we use ANTENNA TUNING to lengthen and shorten antennas ELECTRICALLY to better match the frequency on which we want to transmit. Simply put, the antenna does not physically change length; instead, it is adapted electrically to the output frequency of the transmitter and "appears" to change its physical length. Antenna tuning is done by using antenna couplers.
A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
Melde’s experiment is ideal to study the behavior of standing waves. Students can even visually determine wavelength, period and amplitude of waves. A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems just like the vibrations of a violin or guitar string.
RF signal is coming from an antenna. So it contains electromagnetic waves. But when the signal is processed using electronics circuits, the range of frequency may not be sufficient. So that RF has to be convert to some other frequency acceptable by the circuit. And IF is the intermediate frequency used for tuning & other purpose.
i suggest Johnny was using an A 6 tuning on his stringmaster

what is the reasion of using intermediate frequency in television system
The use of valves changes the length of the tubing and therefore its resonant frequency. Tuning of the instrument is done using either electronic tuners or mechanical tuning forks as a guide to correct pitch then the tuning slide is extended or contracted to set the base pitch. However, its not often for brass instruments to need tuning. They are made in the the key of C as a majority, but have B-flat versions as an alternative. The tuning slide is normally set using the main slide or tube which comes from the mouth piece to the 3rd valve in the first instance. There are 2 other slides that are used that is first valve and 3 valve slide. C-sharp normally requires the 3rd valve extended even if the trumpet is concert tuned.
The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
What frequency are you on?
