As the sound leaves the instrument what is its wavelength in air?

It depends upon the frequency of the notes being played.
Its wavelengths could lie anywhere in the sound spectrum, depending upon the instrument and the artist; from 5 to 10 Hertz ( means 5 to 10 cycles [oscillations of an air wave { passage, past a point in space, by Air that is at times compressed and alternately at times rarified } ] per second ) - up to 15,000 oscillations per second, or Hertz; the approximate maximum upper limit of human auditory capacity.

What does air column mean in musical terms?
Music, like all sound is made up of sound waves traveling through the air. On a string instrument, the sound wave originates with a wave (actually many waves) on a vibrating string. Wind instruments don't have a string, and the sound you hear doesn't sound much like the vibrating reed of a woodwind or the vibrating lips of a brass players. We hear a wave that is established in the air inside the instrument. Of course, air moves through and out of an instrument, but the wave doesn't leave the instrument. A corresponding sound wave, which we hear, is created outside the instrument, but the wave inside the instrument doesn't leave the instrument any more than the wave on a string leaves the string. We need a term to describe the air that is inside the instrument - the air where the wave is established and that term is "column of air."
What is a pasiyok instrument?
Made from leaves of nipa or coconut sound is produced by blowing air on the deed.
What is the wavelength of a sound 110.5 khz?
In air at standard temperature and pressure, it's about 3.1 millimeters ...roughly 1/6 of the shortest wavelength that any human can hear in air.
The pitch of a sound is determined by its wavelength and what?
only wavelengthActually, since ultimately the pitch we hear depends on the frequency, and the frequency is equal to the speed of sound divided by the wavelength, the pitch depends on both the wavelength and the speed of sound. The speed of sound in air depends on the temperature of the air. An approximate formula for calculating the speed of sound (credit Wikipedia) is:cair = 20.0457 x sqrt( T ) m/swhere T is the kelvin temperature.
What statement is true with regards to woodwind instruments?
A sound is produced in a wind instrument when a column of air vibrates inside a tube.A sound is produced when a column of air vibrates inside a tube.
What happens to wavelength as a wave leaves the air and enters the perspex?
The wavelength bends forward as it leaves the air and enters the Perspex. The frequency of the wavelength will also increase.
What determines the highness or lowness of a sound?
Its wavelength, or pitch. Sound is only vibrations in the air. If the wavelength of the vibration is low, then it will sound "high". If the vibration has a high wavelength, then it will sound "low".

Do sound waves have wavelenght?
Yes. The wavelength of a sound is(speed of sound in air)/(frequency of the sound) .
What is the wavelength of sound in the air at 20000 Hz?
1.716cm
When the player blows into the instrument by using the reed what causes the column of air to produce sound?
the sound comes from the vibration of the air as it passes the reed. the pitch of the sound is changed by changing the length of the column (thus forcing the wavelength to become longer) by holding down more keys.
The speed of sound decreases when as the air temperature cools What would this due to the frequency of sound produced by a band instrument?
As air warms up the sound wave will travel faster. The speed of sound in air depends upon the temperature. The warmer the temp., the faster the sound moves. As far as the pitch goes, I think it must depend on the instrument. My guitar goes flat as it gets warm because the strings expand slightly and become longer. In a wind instrument, as the wave travels faster in the instrument, the frequency will increase making the instrument go sharp. The speed of sound is equal to frequency times wavelength, v = f L. The wavelength is determined by the physical size of the instrument and is fixed. So, if velocity increases, and L is fixed, frequency must increase to balance the equation. The higher the frequency, the higher the pitch. So, I guess strings go flat, woodwinds, and brasses get sharp, and percussion depends on the type of instrument, how the sound is physically produced, and what material the sound must travel through.
What happens to the wavelength of a wave as it leaves the air and enters Perspex?
it stays the same
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
What does the musician need to do to produce a sound?
Air && an instrument (;
What is the period of a sound wave whose wavelength is 17.0 m?
Divide the speed of sound by the wavelength, to get the frequency. The period is the reciprocal of the frequency. The speed of sound in air is about 343 meters/second, but it depends on temperature. The speed of sound in other materials is quite different from the speed of sound in air.
A sound wave has a frequency of 3 khz and wavelength 30 cm. how long will it take to travel 1.2 km?
Speed of sound in air isn't affected by frequency and wavelength, but it is of temperature, air pressure and humidity. Generally speaking speed of sound in air is about 340 meters/second.
