When the powerful (nuclear) bomb explodes it generates the shock wave that destroys everything around it. I want to know, does the force of this shock wave depend on the air pressure and density? Imagine that we have got powerful (nuclear) bomb and the object (rocket in this case) that is subjected to this explosion. In all three cases the distance between the bomb and object/rocket is the same-100 km. But there is one difference: 1) In first case both bomb and rocket are placed on the Earth’s surface, so the atmosphere’s (where the shock wave propagates) density and pressure is constant: 2) In the second case the bomb is on the Earth’s surface and rocket is on the 100 km altitude. So, bomb’s shock wave will be spread in relatively dense medium and then in rarified one. 3) In the third case the bomb is on the 100 km altitude and rocket is on the Earth’s surface. So, bomb’s shock wave will be spread in relatively rarified medium and then in dense one. So, my question is: in which case the bomb’s destructive force will be more powerful? Or there will be no difference?
