Finding Sound Velocity in Iron: Examining Dispersion Curves

AI Thread Summary
To find the sound velocity in iron, examining dispersion curves is a viable approach, specifically through the group propagation velocity calculated as vg = dw/dk. The discussion highlights that for audio frequencies, dispersion effects are minimal, making it sufficient to reference established values from tables. Clarification on the purpose of obtaining sound velocity in iron is also sought, indicating potential applications. Overall, the conversation emphasizes the importance of understanding the context and frequency range when determining sound velocity in materials like iron.

I want to define (and find the sound velocity i iron).

can i read it through the dispersion curves of iron?

I am trying to see it through the group propagation velocity, vg = dw/dk, i. e the slope
of the dispersion relation w(k).

am i on the right track?





thanks

I am not sure what are you trying to do.
For what purpose do you need the speed of sound in iron?
For audio frequencies the dispersion is negligible and you can just look up the speed on a table.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
