Ultra sonic waves, sound waves with a frequency too high for the human ear to hear. In general, the average human ear can hear up to 15 KHz, but just about them at a young age may be heard at a frequency higher than this. So by default, the ultra-sonic so often refers to sound waves with frequencies higher than 20 KHz to rise until the amount is not specified limit it causes, bringing waves of the ultra-sonic. used because the waves have direction, allowing us to focus sound waves to target specific needs. This is a feature of the wave form. The waves have a higher frequency, it's even shorter wavelength. If a longer wavelength than the openings (the sound that comes out. ) Of generator frequency sounds, such as the frequency 300 Hz in air to a length of about one meter chip, which is longer than the channels sound waves from the noise generally more waves will be diverted to the outer edge. the origin of the sound waves cause the spread, but higher frequency in the ultra-sonic as 40 KHz wavelengths in air would have only about 8 mm., which is smaller than the opening of the birth. this frequency sound wave is not diffracted by the edges so forth as narrow or as we call it. A direction to the direction of the ultra-sonic sound waves, we implemented a number of actions. Depending on the frequency used by applications such as sound waves travel through the air. Frequency of use is often limited to no more than 50 KHz frequency higher than this because the air will absorb sound waves increases. Thus the strength of the sound waves spaced out sharply reduced. The use of medical needs which can be used for short radius 1 MHz frequency range of 10 MHz while the frequency is GHz (109 Hz), it has been used in many ways. Using the medium of sound waves traveling through the air is not a device that can convert energy into mechanical energy by others to shake back and forth. This causes the ultra sonic sound waves spread in the air, or to convert mechanical energy into another form of energy in it.
