Detonation is a rapid chemical reaction that produces a shock wave, resulting in an explosion. This process occurs when a substance, often an explosive like TNT or dynamite, undergoes a sudden release of energy. The reaction typically happens at supersonic speeds, creating a powerful blast that can cause significant damage. In contrast to deflagration, which is a slower combustion process, detonation is characterized by its high pressure and temperature. The shock wave generated can travel through various materials, making detonation a critical concept in fields such as military applications, construction, and demolition.
