What is the definition of resonance in science?

Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. These are known as the system's resonant frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy. Resonances occur when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a pendulum). However, there are some losses from cycle to cycle, called damping. When damping is small, the resonant frequency is approximately equal to a natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies.


Does a high frequency wave transmit more energy than a low frequency wave?

no.


How you perceive frequency of sound vibration?

With your ears. The faster the vibration, the higher the frequency. A low frequency vibration will be felt more than heard.


Do objects that vibrate quickly have lower frequency?

By vibrating quickly, the wave would have a high frequency.


Which is more energetic a red photon or a blue photon?

The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.

What do you mean by resonance?

Resonant means something vibrates at a given frequency. Usually if you can get an object to resonate at its resonant frequency - it will disintegrate ! For example - if you tap a wine-glass, it 'rings' - that's it's resonant frequency. Now - take a speaker and play the exact frequency through it, while holding it close to the glass - after a few seconds it will shatter because the glass vibrates too fast.


Does the whistle of a teakettle have a greater frequency than a drumbeat and why?

Yes because the sound waves are closer together or more frequent. A drum is usually larger than a teakettle, so it will have a lower resonant frequency.

Resonant frequencies higher than the lowest resonant frequency of a standing wave are called?

In physics the term harmonics is usually used. Note that the lowest-frequency mode also counts as a harmonic: it is simply the first one.


What is the resonant frequency of gold in hertz?

Previous answer: 1,729 MHz There is no "resonant frequency" of gold. Gold does have an NMR frequency, which is 1.729MHz. All NMR frequencies are dependent on the ambient magnetic field, and gold's 1.729MHz is valid for a magnetic field of 2.35 Teslas, which is 45,000 times stronger than a typical Earth field strength. But there is no resonant frequency which, if you broadcast it, will cause gold to resonate.


What is the units of resonance frequency?

Resonance is the tendency for something to oscillate or vibrate at certain frequencies more than other frequencies. The two most recognized and noticeable types of resonance are mechanical and electrical although many other examples may be cited. We are able to notice resonant frequencies in a variety of situations. A string in a musical instrument will vibrate at a specific frequency due to its resonant frequency. A child's swing will move at a constant frequency, also due to the resonant frequency. In electrical circuits, resistance, capacitance and inductance can be used to generate oscillations at certain frequencies.


What is the purpose of resonation?

Resonance describes a 'condition' rather than a 'purpose', but it is made use of in (for example) radio circuits, in order to tune the radio to a particular frequency (the resonant frequency of the signal).


In a tank circuit why can be the energy across the inductor and that of the capacitor not be equal?

When an LC tank is excited at the resonant frequency, the energy across each will be equal (but not necessary equal at a given moment in time). If excited at a frequency other than the resonant frequency, the impedance of the inductor (wjL) and capacitor (1/wjC) will not be equal, therefore energy across each will be different.

How do you dampen the resonant frequency of a speaker cabinet used for playing guitar?

It'd probably be easier to change the fundamental frequency of the cabinet rather than damp it, unless you really want to spend a lot of money. Try sticking a lot of something (try Blue Tack) onto the surface that vibrates. The more you put on, the more you change the fundamental frequency.


How do you configure a monopole antenna on a frequency lower than the resonant frequency?

You can use an inductor or capacitor circuit to electrically lengthen or shorten the antenna. I cant remember which circuit does which but that's how antennas are efficiently used for several frequencies.
