Atomic Explosion -

To trigger this explosion, the fissile material must reach a , where a self-sustaining chain reaction occurs. In modern designs, this is often achieved through:

: Shooting one piece of uranium into another to create a supercritical mass (used in the "Little Boy" bomb). atomic explosion

The following overview summarizes the scientific principles, historical context, and immediate physical effects of an atomic explosion. To trigger this explosion, the fissile material must

: Using conventional high-explosive "lenses" to compress a plutonium core, increasing its density until it becomes supercritical (used in the "Fat Man" bomb and the Trinity test). Physical Effects of the Detonation To trigger this explosion
