What is the so called ‘sound barrier’? And why is there something visible when an Aircraft ‘breaks through’ it? What is it we see? I dont get it at all
In: Physics
It’s not a physical barrier, it’s just a speed, the speed of sound, we say it’s like a barrier because many things change about the airflow once it goes supersonic, a lot of turbulence is created and a loud boom noise can be heard as a supersonic object files past you.
This sonic boom it’s not just when you “break the sound barrier”, it’s constant as the plane flies over new people, because the sound form the plane can’t get ahead of it, when it flies over you it all hits you at once making a boom sound
