What is sonar frequency?
The frequencies on which sonar is used vary widely. Human hearing is usually cited as ranging as from 20 cycles per second (Hertz) to 20,000 cycles per second. There are many sonars that use frequencies in the 20 to 20,000 Hertz range. In general, the sonars that are used for short range underwater applications operate on a slightly higher frequency than those that are designed to look over long distances. But there are a lot of sonars which use frequencies far outside the range of human hearing. Medical imaging is the most popular use of sonar. The range of frequencies used by these devices range from 2 million cycles per second to 18 million cycles per second. These frequencies are far above what humans can hear.
What is the frequency of A flat?
It depends which Ab you mean, the Ab note above middle C is approximately 415 Hertz.
How do you prove that speed equals wavelength times frequency?
Frequency is the number of waves per second, i.e. 20Hz is 20 waves per second. Wavelength is obviously the length of each wave i.e 20m So if there are 20 waves per second, the distance it travels is the length of the wave multiplied by the number of waves in one second. The distance travelled in one second by the wave above is therefore 20 * 20m wich is 400m. The distance travelled in 1 second is 400m. Therefore every second, the wave travels 400m and thus the speed is 400meters per second (400m/s).
What frequency is 1 octave above 600 Hz?
That would be 1200 Hz. Every octave is a superposition of the note below it, so the frequency doubles. The octaves above that would be 2400 Hz, 4800 Hz, and so on...
What does a G major scale look like with two octaves?
If, for example, the lowest G is the first G below middle C, this G would be in the space below the second ledger line below the stave (with the G clef (treble clef). The next note, A, would be on the second ledger line below the stave, the next note, B, will be in the space below the first ledger line, then middle C, and the notes D, E, F and G (that completes the first octave) will be on consecutive spaces and lines above middle C, so that the G completing the first octave will be on the second line on the stave. The second octave will continue with the A in the second space from the bottom, the B on the line above, and the C, D, E and F will be on the consecutive spaces and lines above. The G that completes the second octave will be in the first space above the stave. Also, both F notes will will have a sharp symbol to the left of them ( like a hash sign), unless this symbol appears after the treble clef symbol at the start of each stave.
What is the frequency of the middle note in a musical scale?
The frequency of the middle note in a musical scale is typically around 440 Hz, which is known as the A above middle C.
What is above a waves wavelength?
Above a wave's wavelength is its frequency, which represents the number of wave cycles that pass a fixed point in a unit of time. Frequency and wavelength are inversely proportional in that as wavelength decreases, frequency increases, and vice versa.
The number of cycles per second of alternating current is measured by?
Hertz (Hz). In the US, typical power that comes from wall sockets is 115 V at 60 Hz. One Hertz is "one cycle per second"; it's a basic unit of Frequency. So basically, the power from a wall socket is alternating at the frequency of 60 Hz. Musicians use the A above Middle C as a reference tone, and this note has a frequency of 440 Hz. Humans can hear tones in the range of about 15 Hz to 20,000 Hz. So, if you hooked up your wall power to a speaker (not recommended, obviously), you could hear the frequency.
What is the frequency of a on the piano?
That all depends on which A you're referring to. The first note, at the lowest pitch on the piano is known as Ao, and is 27.5 Hz The next one up the keyboard is A1, andis 55.0 HZ A2 is 110.0 Hz, A3 is 220.0 Hz, A4 (A above middle C) is 440.0 Hz, A5 is 880.0 Hz, A6 is 1760.0 Hz, A7 is 3520.0 Hz.
What is the number of vibrations that occur in one second?
That depends on what kind of a system the local oscillator is part of. In a simple AM receiver, it's typically 455 KHz above the frequency of the incoming signal of interest. In a consumer FM radio, that figure is 10.7 MHz above. In a 'legacy' analog microwave receiver, it's almost always spaced 70 MHz from the received carrier, and since the ubiquitous advent of split-mount digital microwave equipment, with the RF system clamped to the antenna, there's no telling any more ... you always have to look in the book (if that information is even included in the book).

What is the frequency of the highest note on a pipe organ?
The lowest note is the G above middle C, and the highest is the A nine notes above that.
What is pitch of sound?
The pitch of sound refers to how high or low a sound is perceived. It is determined by the frequency of the sound waves, with higher frequencies producing higher pitched sounds and lower frequencies producing lower pitched sounds.
What is the different between frequency and wave length of light?
Frequency refers to the number of wave cycles that pass a specific point in one second, measured in Hertz (Hz), while wavelength is the distance between two corresponding points on a wave, such as between two peaks or two troughs. In relation to light, frequency determines the color of light, where higher frequencies correspond to shorter wavelengths and vise versa.
What is the frequency of A flat?
It depends which Ab you mean, the Ab note above middle C is approximately 415 Hertz.
What hertz frequency is b flat?
According to Wikipedia, the Bb above middle C is roughly about 465 hertz.
What is the 440 in a 440A in music?
440 describes the tuning of the instruments. When the tone A above middle C is tuned to 440 Hertz (cycles of the sound wave per second), and the other notes are tuned in intervals accordingly, it is known as being tuned to 440.
