What are Sound Waves & Why Can't We Hear Some?

AI Thread Summary
Sound waves are vibrations of air particles or other mediums, classified as longitudinal waves consisting of compressions and rarefactions. The human ear detects these vibrations within a specific frequency range, which is why some sounds are inaudible. Frequencies outside this range cannot be perceived, leading to sounds that we cannot hear. Understanding sound waves involves recognizing their physical properties and the limitations of human hearing. This foundational knowledge clarifies the nature of sound and its perception.

hi,

first - i want to tell you I'm pretty good at english, but it's not my mother tongue, and i still use babylon dictionary sometimes, to read answers, and questions. so - i'll have to ask you to lower the english level (not so rich language...). thank's.

second - my question - what are sound waves made of?
and why are there sounds that we can't hear?

thank's
amit

Sound waves are vibrations of air particles (or any other medium, technically). Your ear can detect these vibrations and your barin then interprets that as data, which we call sound. The reason there are sounds that's we can't hears is because you ear can only detect frequcies of a certain range. Anything outside that rage, and it won't be detected.
 
Sorry, just want to add the term :redface:; (since no has done so yet)

*Sound waves are longitudinal waves :smile:

composed of subsequent compressions and rarefactions of particles in a medium

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
