Comparing sound waves to waves in a Coaxial Cable aka T.E.M.

Click For Summary

Homework Help Overview

The discussion revolves around comparing sound waves to transverse electromagnetic (TEM) waves in coaxial cables. The original poster expresses difficulty in finding relevant information about waves in coaxial cables and seeks assistance in understanding the comparison.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants question the meaning of "T" in "TEM" and discuss its implications. There is an exploration of the differences between TEM waves and sound waves, particularly in terms of their propagation in different media.

Discussion Status

Some participants have provided clarifications regarding the terminology and have prompted further inquiry into the differences between sound waves and TEM waves. The discussion is ongoing, with various interpretations being explored.

Contextual Notes

There is mention of assumptions regarding the medium in which sound waves propagate, specifically air, and the conditions of the coaxial cable. Participants are navigating the complexities of these concepts without reaching a definitive conclusion.

Homework Statement



Compare sound waves to waves in coaxial cables a.k.a. T.E.M.

I really have no idea how to answer this question. I've been researching and researching, and so far i can't find any information about WAVES for coaxial cables. Any help?

Thanks.

Let's start with:

What does the "T" in "TEM" stand for? For that matter, the "EM" is another difference.

The T means Transverse am i correct?

Yes. Can you think of a reason why this is different than a sound wave? Well, actually, that is a little bit more complicated, but I don't want to confuse you. Let's just assume sound in a fluid, like air.

I know that air is trapped between the inner and outer conductor, but what i don't know is how their waves are different... I might not be descriptive enough, let me know if I am not.

No, it's not. (at least, not for a good quality one.) Probably, they are asking about a sound wave in the air (not in the coax), and then to compare this to the kinds of wave in a coax that are TEM.
