sonorousnessRESONANCE " The property whereby any vibratory system responds with maximumbounty to an applied force having the a frequency equal to its own."In english, this means that any solid object that is struck with a soundwave of equal sound wave vibrations will amplitude the given tone. This wouldexplain the reason why some singers are able to break wine glasses with theirvoice. The vibrations build up enough to shatter the glass. This is calledRESONANCE.Resonance can be observed on a tube with one end open. Musical tones can beproduces by vibrating columns of air. When air is blown crossways 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 meet themolecules of oncoming air forming a guest at the closed end. When the airreaches the open end, the reflected compression wave becomes a rarefaction. Itbounces back through the tube to the closed end, where it is refle cted. the wavehas now completed a single cycle. It has passed through the tube four timesmaking the closed tube, one fourth the length of a sound wave. By a constantsound frequency, standing waves are produced in the tube. This creates a sublimatetone.We can use this knowledge of one fourth wavelength to create our owndemonstration. It does not sole(prenominal) have to be done using wind, but can also bedemonstrated using tuning forks. If the frequency of the tuning forks is known,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, rest 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 another(prenominal) tuning fork s 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. integrity example of this would bethe human voice. Our vocal chords create sound waves with a given frequency,just like the tuning fork.One of the first applications of the wind factor was done in ancientGreece where the pipes of pan were created.
