acoustics - Does the human body have a resonant frequency? If …
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.
resonance - What is the resonant frequency of liquid water?
Mar 8, 2015 · 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 ...
resonance - Phase difference of driving frequency and oscillating ...
$\begingroup$ In fact, I intended to answer from a similar point of view, but when I was done you had already posted your answer, so I completely changed the scope of mine, since I didn't intend to repeat what you had already said :-P Even if it takes a long time before the external influence starts to increase the energy, in the end the stationary solution would be the same.
waves - Does resonance still occur at half, a quarter, etc. of the ...
Jul 21, 2022 · The maximum amplitude (resonance) is when the driving force equals the natural frequency. [If there are light damping forces the resonance frequency will not quite equal the natural frequency.] There are no other resonance frequencies; the amplitude of the oscillations drops off at an increasing rate as the forcing frequency departs from the ...
Resonating frequencies of atoms - Physics Stack Exchange
Nuclear Magnetic Resonance (NMR) spectroscopy is the first thing that comes to mind for me. The proton (or other nucleus) resonates at a different frequency depending upon what molecule, if any, it is in, magnetic field strength, temperature, and other factors.
Finding the resonance frequency for forced damped oscillations
Dec 11, 2021 · $\omega_d$ 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:
How is energy conserved in resonance? - Physics Stack Exchange
Jan 25, 2016 · 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 ...
What is the reason behind resonance? - Physics Stack Exchange
Apr 8, 2019 · When the driving frequency is way below the resonance frequency, the oscillator oscillates at the driving frequency in-phase (potential term dominates over the inertia term). When the driving frequency is way above the resonance frequency, the oscillator oscillates out-of-phase (picture yourself shaking a pendulum too hard).
definition - How do you define the resonance frequency of a …
Dec 14, 2014 · 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.
Intuitively, what actually is the cause of resonance?
Jan 27, 2021 · Conveniently, this frequency is independent of the amplitude (i.e. how high the pendulum is swinging) and only depends on properties of the system itself. 1 This is called the natural frequency or resonant frequency of the system (there are nuances between these terms that don't matter in this context). So pushing at that frequency will lead to ...
