Do Fresnell equations apply to other waves than EM waves?

[DragonPetter]

When I read about Fresnel equations, I see that it is based on boundary equations determined by Maxwell's equations. So I would think these equations only apply to EM waves.

But is there a similar behavior in other waves like sound waves in water? Would I want to use or modify Fresnel equations for other waves than EM waves?

I'm going to guess that Fresnell equations is only specific to EM waves because it is using the parallel and perpendicular polarization which I think does not apply to sound waves

They only apply to electromagnetic waves.

What does "similar behavior" mean? Half wave loss? Then yes, mechanical waves have half wave loss when reflected on certain conditions too.

Well, by similar behavior, I mean about having a brewster and critical angle, and the same or similar relationships between impedance,transmittance/reflectance, and incident/reflected/transmitted angles.

I am trying to make a ray trace of sound in water, and want to be as comprehensive as possible, so I would like to apply any equations I can.

Also what is half wave loss? Are you referring to phase change on reflections ?

Yes. Or maybe half wave loss is not the correct English name?
