You want to tune a guitar's 'A' string to 440 hz.
That depends on its speed, and therefore on the medium it happens to be in. -- In normal air at sea level, 30 Hz corresponds to a wavelength of about 37.5 feet. -- In copper, 30 Hz corresponds to a wavelength of about 506 feet. -- In diamond, 30 Hz corresponds to a wavelength of about 1,315 feet. -- In water, 30 Hz corresponds to a wavelength of about 160 feet.
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).
For any wave, speed = wavelength x frequency. The speed of sound in air is about 331 m/sec., so the wavelength in this case would be 331 / 100 = 3.31 meters; however, the speed of sound depends on temperature. It also has Avery different values in materials other than air.
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.
440 Hz, 660 Hz, and 880 Hz.
