Resonance

Resonance

RESONANCE: The property whereby any vibratory system responds with

maximum amplitude to an use force having the a frequency equal to its

own.

In english, this means that any solid object that is struck with a give out

turn over of equal sound wave vibrations will amplitude the given tone. This

would explain the fountain why some singers be able to break drink glasses

with their voice. The vibrations build up enough to shatter the glass. This is

called RESONANCE.

Resonance can be observed on a tube with one eradicate open. Musical tones

can be produces by vibrating columns of air. When air is blown crosswise the

top of the open end of a tube, a wave compression passes along the tube.

When it reaches the closed end, it is reflected. The molecules of reflected air

meet the molecules of oncoming air forming a leaf node at the closed end. When

the air reaches the open end, the reflected compression wave becomes a

rarefaction. It bounces back through the tube to the closed end, where it is

reflected. the wave has directly completed a single cycle. It has passed through

the tube four time making the closed tube, one fourth the length of a sound

wave. By a continuous sound frequency, standing waves are produced in the

tube. This creates a pure tone.

We can use this acquaintance of one fourth wavelength to create our own

demonstration. It does not only develop to be done using wind, but can in any case be

demonstrated using correct 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 is

332+0.6T m/s, temperature being, 22 degrees, substitute into the formula.

Calculate 1/4...
