| Feb 2, 2017 at 5:05 | comment | added | SRS | The analog of K for sound waves in a continuous medium is its elastic constant such as the Bulk modulus and the analog of m is the density of that medium. In my case, the medium is a discrete one. | |
| Feb 2, 2017 at 5:01 | comment | added | SRS | @ZeroTheHero The atoms move in the direction of the propagation of the wave. Why would the wave be transverse? Moreover, it is the standard trick to linearize the dispersion relation for the monatomic chain, and read off the velocity of sound from it. | |
| Feb 1, 2017 at 23:49 | comment | added | ZeroTheHero | I just realized I was thinking about your chain incorrectly (of course it can be transverse) yet the question remains: what is the analogue of $K$ in sound waves? | |
| Feb 1, 2017 at 23:04 | comment | added | ZeroTheHero | I'm not the one who downvoted so I can't answer but your question is hard to follow: for a 1d chain of atoms the wave would be transverse, but sound is longitudinal so the two situations don't match much, and my original comment stands: how exactly do you see the connection between atoms connected by springs and sound waves? | |
| Feb 1, 2017 at 22:47 | comment | added | SRS | I would really like to know the reason for the downvotes. | |
| Feb 1, 2017 at 14:19 | comment | added | ZeroTheHero | So maybe you can briefly clarify how you see how a spring constant $K$ and a mass $m$ can possibly enter into the physics of sound wave? | |
