Which terms accurately describe the effects of a high explosive?

High explosives are characterized by their ability to produce a rapid and violent reaction, which results in a shock wave and detonation. When high explosives are initiated, they undergo a chemical reaction that occurs at a speed faster than the speed of sound, creating a shock wave that travels outward from the point of detonation. This shock wave is responsible for much of the damage typically associated with high explosives.

The term "detonation" refers to the explosive reaction that occurs almost instantaneously, producing a significant amount of energy and heat. This high rate of pressure increase and the rapid expansion of gases result in the shock wave that can cause destruction over greater distances. Understanding these two concepts—shock waves and detonation—is crucial for recognizing the potential hazards associated with high explosives in various contexts, including military operations and demolition activities.

In contrast to the other options, the correct answer addresses the specific phenomena associated with high explosives, emphasizing their rapid reaction and resulting shock wave, which are fundamental to their destructive capabilities.
