Right here's What A Nuclear Bomb Really Sounds Like

Utilizing footage of the Upshot–Knothole Annie check detonation, in the above video, you may see the foreboding mushroom cloud first earlier than the jarring and extremely loud sound of the weapon’s detonation. The rationale for it’s because the various speeds of sound and light-weight, which signifies that at a distance, you’ll see a nuclear weapon’s ensuing flash and mushroom cloud earlier than the sound reaches you.

That is the sound of the bomb.”

A lot of the vitality launched by a nuclear bomb is damaged down into three classes, that are blast vitality, nuclear radiation, and thermal vitality. Half of a nuclear bomb’s output comes from the preliminary blast response, whereas the remaining is 35% thermal vitality and 15% nuclear radiation. Nuclear bombs are measured by their yield as it’s in comparison with standard TNT explosives, that means {that a} one kiloton nuclear bomb has the identical quantity of vitality as 1,000 tons of TNT. In different phrases, regardless that nuclear weapons make the most of nuclear fission as their major mechanism, the outcomes nonetheless sound like a standard explosion, albeit on a considerably bigger scale.
