ResonanceRESONANCE " The property whereby any vibratory system responds with maximumamplitude to an applied force having the a frequency equal to its own."In english, this means that any solid object that is touch with a pass awaywave of equal sound wave vibrations get out amplitude the given tone. This wouldexplain the reason why some singers are able to break wine glasses with theirvoice. The vibrations build up plenty to shatter the glass. This is calledRESONANCE.Resonance can be observed on a pipework with one end open. Musical tones can beproduces by vibrating columns of transmit. When air is blown across the top of theopen end of a tube, a wave compression passes along the tube. When it reachesthe closed end, it is reflected. The molecules of reflected air affect themolecules of oncoming air forming a node at the closed end. When the airreaches the open end, the reflected compression wave becomes a rarefaction. Itbounces back by the tube to the closed end, whe re it is reflected. the wavehas now completed a single cycle. It has passed through the tube four timesmaking the closed tube, one twenty-five percent the length of a sound wave. By a continuoussound frequency, standing waves are produced in the tube. This creates a puretone.We can subprogram this knowledge of one fourth wavelength to create our owndemonstration. It does not but have to be through using wind, but can in addition bedemonstrated using tuning classifys. If the frequency of the tuning forks is known, consequently v=f(wavelength) can find you the length of your air column.Using a tuning fork of frequency 512 c/s, and the speed of sound is332+0.6T m/s, temperature being, 22 degrees, substitute into the formula.Calculate 1/4 wavelengthV=f(wavelength)wavelength=V/f=345.2 (m/s) / 512 (c/s)=0.674 m/c1/4 wave. =0.674 (m/c) / 4= 0.168 m/cTherefore the pure tone of a tuning fork with frequency 512 c/s in a temperatureof 22 degrees would be 16.8 cm. The pure tone is C.If thi s was done with other tuning forks with frequencies of 480, 426.7,384, 341.3, 320, 288, and 256 c/s then a scale in the key of C would be produced.There are many applications of this in nature. One example of this would bethe human voice. Our vocal chords create sound waves with a given frequency, in effect(p) like the tuning fork.One of the first applications of the wind instrument was done in ancientGreece where the pipes of pan were created.
