That would also depend on the speed. Note that sound can go at quite different speeds, depending on the medium and the temperature. Use the formula speed (of sound) = frequency x wavelength. Solving for wavelength: wavelength = speed / frequency. If the speed is in meters / second, and the frequency in Hertz, then the wavelength will be in meters.
The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.
440 cycles per second. 1 Hz = 1 cycle per second
The fundamental is the lowest frequency; the harmonics are all multiples of that frequency. For example, if you play a concert A (440Hz) on a trumpet, the harmonics of that tone would be at 880, 1320, 1760, 2200, 2640, 3080, 3520, 3960, 4400Hz, and so on.In most cases, people do not perceive the harmonics as separate pitches, but as part of the sound. They give the tone its distinctive timbre--in this example, the sound of a trumpet. However, if there are objects nearby, such as strings, bells or even glassware, which are resonant at one of the harmonic frequencies, they can be excited by the tone and will continue to "ring" after the note stops. A resonant filter can be used to pick out the harmonics, as well. The harmonics can also be visualized on an audio spectrometer.Harmonics are not limited to sound waves; they can be present in any periodic motion or waveform, including radio waves.
The greater the number the higher the frequency. Zero frequency is called DC in electricity. Audio frequencies start at 20 Hz (Hertz= cycles per second) and go up to 20,000 Hz. Adults usually can't hear above 12,000 Hz so this is why the teenagers use a ring tone of 13,000 Hz while in school. The teachers can't hear it. Refer to kHz which is 1,000 Hz. There for 20 kHz is 20,000 Hz.
440
Absolutely 440 Hz is the frequency of the A note that is 1½ steps below middle C, the top line of the bass clef. 880 Hz is the frequency of the A note one octave higher, the second space from the bottom of the treble clef. On a piano, if you slam hard on the lower of those two A keys and just lightly press the higher one, the 440-Hz sound will be louder than the 880-Hz sound. The loudness, or amplitude, of a sound wave has to do with how tightly the air molecules (or the molecules of whatever the sound-propagating medium is) are packed in each wave of the sound, while the sound's frequency or pitch has to do with how frequently the waves are generated (440 times per second in the case of a 440-Hz sound), or how far apart the waves are (frequency is inversely proportional to wavelength).
880
880 yards = .5 miles
880 is, if you think about it, exactly half of 1760.
1416.22 kilometres is 880 miles.
The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.
Answer: 880 acres = 1.375 mi²
880
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.
.5 miles
Yes. It's exactly one octave lower.
0.5 miles = 880 yards.
