2015年3月8日 · What is important in the idea of resonance with water is to establish a frequency of excitation that causes the natural frequencies to superimpose or wave superposition. By achieving wave superposition the amplitude of the oscillations will have the greatest potential of breaking the molecule into its elemental constituents thereby creating ...

2014年12月14日 · When it comes to electrical systems eg a series LCR circuit the parameter which is often measured is the current and the frequency at which current resonance occurs is the natural frequency of undamped oscillations of the system $\omega_0$ and as such the frequency for current resonance does not vary with damping.

Discussion of human resonant frequency. also found here. "...found the human whole-body fundamental resonant frequency to be around 5 Hz. However, in recent years, an indirect method has been prosed which appears to increase the resonant frequency to approximately 10 Hz. To explain this discrepancy, experimental work was carried out in NTU.

2015年6月25日 · The resonant, frequency is the frequency at which an object tends to vibrate. Every rigid object in existence has a natural structural resonance frequency, a frequency at which it, metaphorically speaking, wants to shake more than any other. If you vibrate an object at its resonant frequency, it will gradually shake more and more wildly.

2015年5月19日 · I'm wondering, since an electron has a resonant frequency, and so does a system of water molecules, brick, person, and planet; how would an incoming vibrational wave of infinite 'Q' (so basically it has a very accurate and narrow bandwidth resonant frequency) tell the difference between two objects of the same resonant frequency?

2016年1月25日 · However amplitude resonance occurs when the frequency of the driveR is equal to the natural frequency of the driveN system which if there is damping is $\omega_d$. There are other types of resonance. One is velocity resonance – the speed of the driveN system is a maximum and this occurs at the natural frequency of the undamped driven system ...

2015年10月24日 · For velocity and current resonance the resonant frequency is the natural frequency of the undamped driven system and does not depend on the amount of damping. For amplitude resonance there is a possibility of confusion about what is meant by the natural (unforced) frequency of the system because there are two ways of defining the frequency of ...

2019年9月1日 · The resonance frequency of a steel ball Hot Network Questions Can I enter the UK with an accompanied child visa when the person on my visa changed their passport number?

2021年12月11日 · $\omega_d$ is the frequency of damped oscillations, i.e. when $0<b<2m\omega_0$ $\omega_r$ is the frequency at which system gain is maximum, aka resonant frequency; The resonant frequency is not equal to the natural frequency except for undamped oscillators which exist only in theory. Here is a physical (intuitive) explanation:
