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.

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 ...

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 ...

Is there a generalization of mode coupling theory?
I am currently reading a lecture on coupled-modes theory and have a question regarding the ansatz:
$$E_\text{tot}=A(z)E_1(x,y,z) + B(z)E_2(x,y,z) \\ H_\text{tot}=A(z)H_1(x,y,z) + B(z)H_2(x,y,z)$$
and

How does a guitar string produce sound?
I'm curious about the mechanism of a guitar producing sound. Of course, I know once a string is plucked it vibrates in a superposition of several harmonics, but what I don't know is what happens next. ...

Describing two levels of a spin 1 triplet with zero field splitting as an effective spin 1/2
I am working with NV centers and there one can describe the groundstate triplet of the system with a Hamiltonian of the form:
\begin{equation}
H_e = D \hat{S_z}^2 + g \mu_B ( B_x \hat{S_x} + B_y \hat{...

Resonant frequency of multi diameter closed pipe
I'm trying to make sense of how resonances in pipes work.
I gather that, in the instance below, the fundamental resonant frequency of the 1m closed pipe (ignoring end correction etc.) is
$$ f_{0} = \...
