Okay if you are talking about sound waves, they’re not really waves in the traditional sense. They are waves because it tracks the compactness/vibrations.
The reason why sound transfers faster in solids is because the atoms are more rigid due to, you know, being a solid.
If you pump enough energy into it, won’t you start doing funny things?
Ie: if you put enough energy into a rigid material there’s a point where it stops being able to take the force and breaks
I’m also not a scientist and also am the wrong type of engineer too so…
I’d imagine if you compact things faster than the energy can leave the immediate area, you’d run into funny phenomenons with the temperature/pressure/state of matter histogram.
Which brings me to my question of what is a shock wave if not a sound wave?
