A system can have more than one resonant frequency if it has multiple modes of vibration that can be excited. Each mode will have its own natural frequency at which it resonates. This can happen in systems with complex geometries or multiple components interacting with each other.

What does it mean by 'above and below resonance?
'Above resonance' means a frequency higher than the resonant frequency of a system, while 'below resonance' means a frequency lower than the resonant frequency. At resonance, a system vibrates with maximum amplitude, making these concepts important in understanding the behavior of vibrating systems like simple harmonic oscillators.
What is the definition of resonance in science?
Resonance in science refers to a phenomenon where a system (such as an object or an atom) oscillates at a specific frequency when subjected to an external force of the same frequency. This results in an amplification of the vibration or energy of the system. Resonance plays a key role in various scientific fields, including physics, chemistry, and engineering.
Is Natural frequency and Resonance of a Cantilever Beam will be same?
No, the natural frequency and resonance frequency of a cantilever beam are not necessarily the same. The natural frequency is the frequency at which a system oscillates without any external forces, while the resonance frequency is the frequency at which a system is most responsive to external forces. In a cantilever beam, the resonance frequency is typically higher than the natural frequency.
Which will have more energy a high frequency waves or a low-frequency wave?
High frequency waves will have more energy than low-frequency waves. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
What are the highest-frequency and and the lowest-frequency parts of the EM system?
The highest frequency electromagnetic waves are gamma rays, which have wavelengths shorter than 10 picometers. The lowest frequency electromagnetic waves are radio waves, which have wavelengths longer than 1 millimeter.

Resonant frequencies higher than the lowest resonant frequency of a standing wave is called?
harmonics
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.
How could you find the sound frequency to break a glass?
High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
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.
