What is the definition of resonance?
In physics, resonance is the tendency of a system to oscillate at maximum amplitude at certain frequencies. In music, resonance is the characteristic of sound waves vibrating in either the open air or within an enclosed structure, which can include a musical instrument. Like in a violin, when the strings are bowed, the sound resonates within the box (the hollow part of the instrument) and thus becomes a bit more amplified for us to hear. The Link below gives a simple and lively explanation of the concept of resonance. http://analog-design-for-chickenbrain.blogspot.com/2009/05/what-heck-is-resonance.html

Resonance can occur when an object vibrates at another objects resonant frequency.
No, it does not. It contains all single bonds.
Resonance is actually the tendency of vibrating body to increase its amplitude when applied frequency becomes equal to its natural frequency. When we apply a frequency equal t…o the natural frequency of vibrating body (i.e by giving a push to a swing FOR EXAMPLE). This push (force) makes amplitude double. Because Amplitude directly varies with Force but Time Period or Frequency does not change.
redistribution of electron that can take place in unsaturated tertialy in conjugated system where pi bond involve called resonance or mesomeric effect .
In acousitcs, a device used to increase resonance(like echo effects) of a soud and usually apparent volume there are both acoustic(on some guitars such as the Resophonic) and …electronic resonators. Of course if you recorxed in a bent conrete tunnel like those culverts in central park this would be a natural resonator llike the higher noise of a train in a tunnel, the sound reverberating off the walls. Phil Spector made good use of resonance and(wall of Sound) in his recordings many of which could not be performed live for optimum effect. crimson and clover has resonator effects. On an automobile it is a devise , like a muffler, used to lower the sound output.
For a series a.c. circuit, resonance occurs when the inductive reactance is equal to the capacitive reactance. You can work out the frequency at which this occurs by inserting… the variables into the following equation: XL = XC
Brand resonance refers to the nature of the ultimate relationship and level of identification that the customer has with the brand.

Making music, notes are picked by the resonant frequencies of the strings or tubes of each instrument. Microwave ovens excite water molecules in your food at their resonant fr…equency so your food is warmed more effectively. Magnetic Resonance Imaging machines (MRI) exploit resonance in hydrogen molecules in your body to identify different types of tissue. 'WiTricity' is a form of wireless energy transfer that exploits magnetic resonance to transfer electricity between coils over greater distances.
The frequency at which the impedance of the circuit becomes zero is known as resonance frequency. Actually at resonance resistance only presence in the circuit. That means th…e impedance of the inductor and capacitor will automatically vanish.
A resonance structure is an alternate way of drawing a Lewis dot structure for a compound. For some molecules, there are multiple ways to draw a Lewis dot structure that still… satisfy the rules (for instance, having the correct total electron count and satisfying the octet rule on each atom). Benzene is a classic example where a resonance structure is used. See the Web Links to the left for a diagram of benzene's two resonance structures. Note that in both cases, there are alternating double and single bonds between the six carbons. What changes in the two structures is which bonds are single and which are double bonds. In reality, all the bonds in benzene are identical. They are neither single nor double bonds, but something like a "one-and-a-half bond." There is a common misconception that in reality the molecule is somehow alternating between the two structures. It is not.. This is extremely important to understand! Resonance structures are simply a tool to make up for the fact that Lewis dot structures are not the best tool for describing bonding in molecules (they are very good, just not perfect!). Using resonance structures is a kind of band-aid to patch up this shortcoming of Lewis dot structures (for a better representation of bonding, you must use molecular orbital theory which requires quantum mechanics!). So if the is not alternating between the two structures, what's going on?! In fact the molecule's structure is always the same. The actual bonding the molecule is a mixture of the different resonance structures all the time. To see this, you have to look at the different structures and imagine blending them together to give one single structure which has contributions from each structure. So the bonds in benzene are not going back and forth being single and double bonds. Not at all! Not even really quickly. Instead the bonds are ALWAYS this average bond which is a bit of both single and double. Note also that not all resonance structures contribute equally to what the molecule really looks like. For benzene, there are two structures, and the real molecule is a perfect mixture of both structures, 50% each. However, the are some molecules for which you can draw more than a dozen structures! In this case, you might have one structure that is dominant, and the real molecule's structure is close to that, and the other structures only contribute a little bit. In other words, the real structure is a weighted average of all the different resonance structures, but the weighting for each structure depends on the details of that structure, and some have very little weighting. How do you tell what structures are more important that other ones? Only if the structures are identical by symmetry, like for benzene, do they contribute exactly the same amount. Another way to say this is that if you can convert between two structures just by rotating the drawing around, they are the same by symmetry. However, sometimes they are not the same at all. Here is how you tell. A better resonance structure has the following properties: -- bond is maximized -- formal charges are minimized -- negative formal charges are carried by the most electronegative atoms There is no way to predict exactly how much each structure will contribute (except when two are equal by symmetry). But you can put them in order based on the three rules above (and they are listed in order of importance).
Resonance is when a system oscillates at a particular frequency with more amplitude more readily than others. Electrical resonance occurs when the impedance is at a minimum (f…or a series circuit) or at a maximum (for a parallel circuit).
They are combination of converter topologies or switching strategies that result in zero voltage and/or zero current switchings.
Literally, 'ample resonance' means 'full or satisfactoryconnection.' In a literary or academic context, one may use thisphrase to speak of the 'full or satisfactory connection…' of atext's concepts, themes, tensions, etc., to either other texts orto reality -- or to both.
The difference between the energy content of the resonance hybrid and other cononical structure having least energy is called resonance energy.
resonance forms are individual lewis structure in cases where two or more lewis structure are equally good descriptions of a single molecule .
