    Hello!

    I have heard of three kinds of generating frequencies, by sound, by electricity and by mehacnicle way. but I have no idea how they look how to be used, so my question is simply when you re talking about generate vibration frequencies, How do I produce them? is there an another way BTW?

    hope you understand :)

    Frequencies of WHAT?
    Light has a frequency, as does sound and many other things.

    frequency is a cycle of something per unit of time ... anything can have a frequency

    Radio frequencies I think he is asking about that's why I gave those links.

    thanx Cosmictraveler, nice name:)
    gonan check the sites!
    well I was reffering to vbration, i want to be able to vibrate matter at high and low frequencies , metalls paper wood you name it..

    can radio frequencies do this, i heard sound can do it?

    The obvious question would be: why?

    For mechanical, you could use a motor with a variable rheostat and an unbalanced drive shaft or weight mounted on there.

    "generating a frequency" usually refers to electronics, therefor what you need is some form of oscillator.. frequency is measured in cycles per second and is called hertz. for example, if you have an oscillator that produces 56 cycles per second then it is said to produce 56 hertz. you can also add kilo and mega in front of hertz. example for 1000 cycles per second it's called 1 kilohertz or 1 khz, for 1 million cycles per second it's 1 megahertz or 1 mhz.

    oscillators come in many different flavors. there are sine, square wave, ramp, and sawtooth oscillators.
    sine wave oscillators depend heavily on inductance to produce the wave.
    the rest rely mostly on the charge on a capacitor to create the waveform
    the exception is the squarewave oscillator. this one is also known as a special kind of flip-flop. it's used almost exclusively in the clock circuits of computers and provides the timing for them.

    I generate "good vibrations" by listening to the "Beach Boys". :)

    variable rheostat is redundant. a rheostat IS variable, therefor it's just "rheostat"

    that is what I am talking about folks now I wonder how did tey do that, was just really sound? and about the "oscillator" i searched it up and dont quite get it is it electronic and can it produce the same effects as the last video showed?

    thanx

    check out post 8.
    mount the motor to the underside of the plate of steel. use the rheostat to vary the frequency.

    ok doki, lets make it easy, basicaly I want to vibrate aluminum foil at a 18khz for example, right?

    so first question that comes now? what method of frequency generating is the to be used?
    sound, oscillator, H.frequ. current, radio?
    and how would i do?
    I am googling a lot right now but it is very hard without a help of intelligent peoble like you:D
    sorry so much but I am a bit confused peoble

    as in the videos they use sound to resonate ..


    thanx alot

    The device you are looking for is called a tonoscope.

    For the photographs on this site, a small (0.2 g) magnet was fixed to the plate. An oscillating magnetic field (provided by a coil connected to an audio amplifier and a signal generator) is used to provide an oscillating force whose frequency is tuned to the resonance of the mode.

    I looked around, but no one seems to sell them.

    Did you mean teinoscope (in dictionary) or Monoscope (in encyclopedia)?

    Dictionary suggestions:
    teinoscope
    conoscope
    monoscope
    toposcope
    townscape
    anoscope
    gonioscope
    phonoscope
    manoscope
