Hello!
I'm getting a bit confused with how to deal with sound waves that are within one critical bandwidth of each other.
I do not fully understand how you are meant to combine the intensities of sound waves when they lie within one critical bandwidth?! I would really appreciate some...
Hello!
I'm getting muddled with the notation in my notes, in which I have
\overline{(E-\overline{E})(P-\overline{P})}
From which you can get
\overline{EP} - \overline{E} \ \overline{P}
I can see where these come from, but not where the
\overline{E \overline{P}} - \overline{\overline{E}...
Great, thanks! With that further approximation that the sound waves are adiabatic, PV^{\gamma} = constant, does that also then put limitations on the pressures that can be described by the acoustic equation?
So when considering the higher pressure waves, you would derive an acoustics wave equation in which you didn't make small amplitude waves approximations? I get it now! Thank you :-)
Hello!
When considering the acoustics wave equation
\frac{\partial^{2}P}{\partial t^{2}} = c^{2} \nabla^{2} P
I don't really understand why you can say that the applicability of this equation varies for different sound pressure levels. I don't see why this shouldn't hold for all...
Hey
Just wondering why atoms in liquids can be considered classically
If you compare the deBroglie wavelength with the atomic spacing, I understand that the deBroglie wavelength should be much smaller than the spacing.
But how could you show that?
If
\lambda = \frac{h}{mv}
How...
