How to find or measure the resonant frequency of any object?

You musto to produces vibrations in your objeect, but you need a method to:\n\n1. producing vibration of differents frequencies\n2. A equiptment to measured the amplitud of the vibrations\n\nWhen the amplitud is big, you found the resonance frequency.\n\nYou should to observe that this maximum not occur at all frequencies, only a certain frequencies.\n\nOr you use a "stroboscopy light " to do it... produces the vibartion in your object and measure the vibration changing the stroboscopy frequency light.

f = v / lambda -> lambda = v / f\n\nv = velocity\nf = frequency\nlambda = wavelenght\nv in vacuum = c = 3 x 10^8 m/s\n\nlambda = 3 x 10^8 / 6 x 10^14 = 0.5 x 10^-6 m= 500 x 10^-9 m = 500 nm

Use an RF Spectrum Analyzer to detect and locate any device emitting a radio signal.  Spectrum analyzers tend to be extremely expensive and might have a lengthy learning curve if you're not familiar with radio physics.  There might be cheaper ways, but I doubt there is any other way that is as reliable as a spectrum analyzer.

Go to this site http://www.bksv.com/pdf/Measuring_Vibration.pdf it should help you out with your question.

you can take a graduated cylinder. fill it with an mount of water to be above object. measure water-write,. now, place object in cylinder. now, record new volume. now, subtract old- new. thi will give you the volume of the irregular object itself. hope this helps!

yes you can. For real low freq. you can actually do a DC measurement. Just slow the sweep rate way down and you will see it.

Sure, I have a scanner and the website I use to find frequencys is http://www.radioreference.com/modules.php?name=RR&stid=17 . \n\nHope that Helps :)

b. 93,300,000 Hz\n\nFM stations measure their frequencies in Megahertz (MHz)

here you go:\n\nhttp://images.google.com/images?svnum=10&hl=en&q=electromagnetic+spectrum&spell=1\n\nit contains all frequencies

Radio shack has a book (about $20) that has every freq you could ever need in it , even your local #'s

Optical Spectrum Analyzer (OSA) is probably what you're looking for...nice for discovering chemical composition of light source and probably a zillion other different things.

Frequency is measured in Hertz, or inverse seconds.  So take the inverse of 6, which would be 1/6, which is your frequency.  Tada!

Hello, here is what you need:\n\nEnergy = Planck Constant * Frequency\n\nE = h * f\n\nh = 66.26 x 10^-34 Joule second

For (a), with a nat. freq. of 100 rad/s or about 16 Hz, the measurement error is bound to be greater than 5% at the upper range of the excitation, 40 Hz.\nFor (b), the necessary equations are found in the reference. First solve for the natural frequency of the mass-stiffness w0 using eq. 5. Then iterate eq. 7 to find the maximum Q needed for a TR = 0.3 at w = 30 Hz. Finally use eqs. 6 to get the needed damping ratio zeta.

E = 1/2 M x v^2 x F x H \n \nWhere v is the velocity of the load hitting the surface and H is the time period in which the frequency continues.
