Airblast is defined as?

• A. Pressure wave from a blast traveling through the atmosphere
• B. The shock wave in rock
• C. The heat from the explosion
• D. The light from the detonation

Answer: (A)

Airblast refers to the atmospheric pressure pulse produced by an explosion. When a blast occurs, rapidly expanding gases push on the surrounding air, creating a shock-like pressure wave that travels through the atmosphere outward from the detonation. This is the pressure wave you feel and hear at distance, and it can cause cracking or breaking of windows and other sensitive structures. The other effects describe different phenomena: a shock wave in rock is ground shock, which travels through the earth rather than through air; the heat from the explosion is thermal energy transferred as heat rather than a moving pressure wave; and the light is optical radiation, not the pressure pulse in air.
