### How Do Soundwaves Move and Influence Specific Particles or Gases? Natural Resonant Frequencies?

If you read this link your questions can be answered . Formation of the inversion layer causes a lack of vertical movement of the atmosphere and the occurrence of long-lasting high concentrations of ...

### Virtual photons and slowing down longitudinal wave propagation

2.) Suppose the charge shift in the rod follows a sine movement. Then a longitudinal wave will propagate. Is there a possibility to slow down the speed of this propagation? How is a radio wave ...

### How does an electron wave move between locations in QFT?

The idea of a quantum field as a bunch of oscillators is really quite bad an analogy if you want to use it to reason about how quantum field theory actually works, see this question and this question. ...

### Intuitive understanding of the unit $kg/s^3$ — the unit of sound volume

Not every combination of base units has a clear physical meaning. The best way to understand any quantity is to look at the equation that produces it. For instance in your case sound intensity $I$ ...

### Double Slit Thought Experiment to Account for the Particles that Don't Go Through the Slits

The root of your question is that you are thinking because there is "interference" particles are cancelling and therefore there should be less of them ....? Electrons are particles and they ...

### Optimal Way for Transmission of Sound from Air to Water

You could try a horn from a horn speaker in reverse. The horn acts as a transformer between the speaker diaphragm and the much lower impedance outside air. The sound pressure is much higher at the ...

### What does the wave created during refraction look like?

The interference is due to a shift in the phase. There is no change in frequency (assuming ordinary refraction, and not another phenomenon such as fluorescence). An electron bound to an atom can be ...

### Double Slit Thought Experiment to Account for the Particles that Don't Go Through the Slits

Do I have the correct rough detection patterns at both A and B in both the W and P setups? Yes (though it would of course be strictly zero where the slits are) Will the total number of detections N ...

### Plane waves in terms of spherical waves in 2D

3D Case: your expansion is wrong The expression you wrote is not right, here is the correct expansion: using spherical coordinates $(r,\theta, \phi)$, there is something called partial wave ...

### What does the wave look like during refraction?

Actually, the wavelength itself decreases when the ray travels into the denser medium, since the speed of the ray decreases and the wavelength must also decrease given the frequency stays constant. ...

### How do we deal with doppler effect in $3D$ space?

If $\hat{r}$ is a unit vector pointing from the source to the receiver, then $v_s \cos \theta = \hat{r} \cdot \vec{v}_s$, where $\vec{v}_s$ is the velocity vector of the source. So the natural ...

### ODE solutions for a driven oscillator in higher resonance modes

The full solution is $y(t) = \dfrac{\sin (\omega t) -\omega t \cos (\omega t)}{2 m \omega ^2}$ where $\omega^2 = \dfrac km$. It may not look dimensionally correct but one must remember that there is a ...

### ODE solutions for a driven oscillator in higher resonance modes

An oscillating system may have numerous resonances, but not that system! That ODE represents a driven harmonic oscillator with exactly one resonant frequency and, indeed, if you apply an out-of-...

### Physical manifestation of mechanical waves for a non-defined value of the cotangent function

Short Answer: Real life would kick in, and the rod would vibrate in a slightly different manner than this theory would suggest. Longer Answer: The wave equation is a mathematical idealization that ...

### Physical manifestation of mechanical waves for a non-defined value of the cotangent function

You would be at resonance. The amplitude of the wave would grow with time to the point at which the linear wave equation is no longer a good approximation.
