ResonanceRESONANCE " The property whereby any moving system responds with maximumamplitude to an applied force having the a oftenness equal to its own."In english, this means that any solid object that is potty with a laboriouswave of equal sound wave vibrations willing amplitude the given tone. This wouldexplain the reason why some singers argon able to break wine glasses with theirvoice. The vibrations build up decent to shatter the glass. This is calledRESONANCE.Resonance can be observed on a underground with one end open. Musical tones can beproduces by vibrating columns of personal line of credit. 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 flirt 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 through with(pred icate) the tube to the closed end, where it is reflected. the wavehas now completed a single cycle. It has passed through the tube four timesmaking the closed tube, one one-fourth the length of a sound wave. By a continuoussound frequency, standing waves are produced in the tube. This creates a puretone.We can map this knowledge of one fourth wavelength to create our owndemonstration. It does not save have to be make using wind, but can in like manner bedemonstrated using tuning severalises. If the frequency of the tuning forks is known, and then 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 this 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, notwithstanding like the tuning fork.One of the first applications of the wind instrument was done in ancientGreece where the pipes of pan were created.
