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...
If middle C is 513 hz (which it is not), then A above would be 513*23/4 = 862.8 hz.
frequency [Hz] = velocity[m/s] / wavelength [m] frequency [Hz] = 24 [m/s] / 3 [m] frequency = 8 [Hz]
Hertz(Hz)
Frequency = reciprocal of period = 1/P = 1/0.008 = 125 Hz.
Hz is short for hertz. It is not a time, but a frequency. Time is measured in seconds, Hz is equivalent to 1/seconds. Therefore, you can't convert between time and frequency.
That is 600 Hz as an octave is defined as a doubling of frequency
One octave above 300 Hz = 600 Hz. One octave below 300 Hz = 150 Hz.
150 Hz
The frequency of a C of the fourth octave is approximately 261.626 Hz.
1 KHz.
That is correct. 262 Hz is the frequency of the note "middle C" on a piano keyboard, while 880 Hz is the frequency of the note A one octave above the note A above middle C on a piano keyboard.
The term 'octave' is the name for an interval(space) between two notes. The frequency of the note is doubled, or halved, depending on whether the interval goes up or down in frequency. The two notes are heard toghether as the same, and will also have the same name. For example, an octave above A(440 Hz) is A(880 Hz) an octave under A(440 Hz) is A(220 Hz) To answer the question, the similarity between the keynote and an octave above it, is that the ratio between the frequency of these notes is 1:2 and of course, their names.
The frequency of a sound wave affects the pitch of a sound. A higher frequency sound wave produces a higher pitch sound. On a piano, the pitch A4 (A above "middle C") will produce a soundwave with a frequency of 440 Hz. The pitch A3 (A an octave below A4) will have a frequency of 220 Hz. The frequency of A5 (A an octave above A4) is 880Hz. "Midde C," or C4, has a frequency of approximately 262 Hz.
the frequency of a wave changes the pitch of the of the sound, a lower frequency (less frequent vibrations of the speaker) means lower pitch (bass notes) a higher frequency increases the pitch (treble notes) the formula is: speed = frequency x wavelength note: if you double the frequency of a sound you half the wavelength (assuming the medium through which the sound travels is constant, thus the speed of the sound is constant) doubling the frequency also increases the pitch by one octave... the note "Middle C" is 440 Hz "C" one octave higher is 880 Hz and "C" one octave lower is 220 Hz all of the "C" notes in the musical scale are "C" below human hearing range 13.75 Hz Lowest "C" 27.5 Hz (Just within average human hearing range) "C" One Octave Higher 55 Hz "C" One more Octave Higher 110 Hz "C" One more Octave Higher 220 Hz "C" One more Octave Higher 440 Hz also known as "Middle C" "C" One more Octave Higher 880 Hz "C" One more Octave Higher 1760 Hz "C" One more Octave Higher 3520 Hz "C" One more Octave Higher 14080 Hz (The Highest "C" Note the average human can hear) "C" One more Octave Higher 28160 Hz (outside of human hearing range but it really annoys dogs)
Higher notes have higher frequencies. A typical tuning fork vibrates at 440 Hertz. That's the tone of the A above middle-C on a piano. The A one octave higher is 880 Hz (2 x 440 Hz). The A one octave above that is 1760 Hz (2 x 880 Hz). The A below middle-C is 220 Hz (440 Hz ÷ 2), the next lower A is 110 Hz, and so on. The lowest note on a piano is 27½ Hz, and the highest is 4186 Hz.
An octave is a factor of 2 in the frequency. So, just divide 1200 Hz. by 2, then divide the result by 2 again.
