A cracking furnace exploded in a petrochemical industry building near my city somedays ago. The building is more or less far from the city, and even so people could notice the explosion. The windows shook and some of them broke. Thank God, there were no injuries. But the accident made me think a lot of things and I wanted to share them with you because you may solve some of my doubts.
what kind of wave was the responsible for breaking the windows? Was it a shockwave? Or a soundwave? Was it travelling at the speed of sound?
I noticed the wave when it reached my house because I saw the windows shake, but I didn't feel anything in my body, why?
As I've said, there were no injuries, not even people who were working there. But why was that? Because the wave was very strong, that's why the whole city felt it. Also, ears are always the most affected organs and people who were near the explosion were said to be "stunned" after the accident, why?
Waves don't carry matter, just energy, so the medium shouldn't move. But the broken glass obvioulsy moved... doesn't that contradict the theory? Obviously theory is never contradicted, but what's the explanation?
suppose that there exists such a "strong" wave that can push a person... does it mean that the wave amplitud was "big"? Or was its frequency high? Because, according to Planck's equation, the more frequency, the more energy.
Why didn't the wave reflect off the house wall when it hit it and return to its original source?
