# Questions tagged [resonance]

Resonance is a characteristic of physical systems having a structure that allows energy to flow between various states at a specific, oscillatory rate (resonant frequency). For a stable resonant system at steady state the internal energy is either fixed without losses or the rate of energy input is equal to the energy losses.

### How big can a current resonance possibly get and what are the sources of power loss?

A damped spring coupled to a sinusoidal force follows the differential equation $$\ddot{x}+2\beta\dot{x}+\omega_0^2 x = f\cos\omega t .$$ It's well known that the amplitude of the spring in the ...

### What really is natural frequency and resonance?

Shouldn’t the frequency of an object depend on how much I push it from one end if the other end is attached? And what’s resonance? In my textbook there is no such explanation to what is actually is ...

### Question on 1D Scattering Resonances

I'm reading Henley and Garcia's Subatomic Physics. To introduce the concept of resonances they use a 1D square well scattering example. Resonances are where the transmission coefficient goes to one. ...

### How exactly does a seashell make the humming sound?

My little brother asked me where the ocean-like sounds came from inside of a sea shell. I told him that the air trapped inside the shell vibrates, making a sound. But then he asked me why the air had ...

### Why do we get overtones in a high-overtone bulk acoustic (HBAR) resonator?

In HBAR we tend to observe a base resonant frequency and then overtones at higher frequencies. Why can't we have just one standing waves in between the top and bottom electrode? What causes the ...

### How does acoustic transducers have multiple resonances?

I am working with determining the variation of impedance of acoustic transducer with frequency. Below is the Van Dyke equivalent model of the transducer. By analyzing this transducer equivalent model ...

### Resonating string with increasing amplitude

The situation goes like this: We have a tuning fork at one end of a string (whose other end is fixed to a wall and length $L$). The fork is vibrating with small amplitude so we approximate this end of ...
