A stun grenade, also known as a flash grenade, flashbang, thunderflash, or sound bomb, [1] is a non-lethal explosive device used to temporarily disorient an enemy's senses. Upon detonation, a stun grenade produces a blinding flash of light and an extremely loud "bang".
A blast wave travels faster than the speed of sound, and the passage of the shock wave usually lasts only a few milliseconds. Like other types of explosions, a blast wave can also cause damage to things and people by the blast wind, debris, and fires. The original explosion will send out fragments that travel very fast.
Consider a strong explosion (such as nuclear bombs) that releases a large amount of energy in a small volume during a short time interval. This will create a strong spherical shock wave propagating outwards from the explosion center. The self-similar solution tries to describe the flow when the shock wave has moved through a distance that is ...
At the explosion of nuclear bombs lightning discharges sometimes occur. [40] Smoke trails are often seen in photographs of nuclear explosions. These are not from the explosion; they are left by sounding rockets launched just prior to detonation. These trails allow observation of the blast's normally invisible shock wave in the moments following ...
Weighing 14 pounds and responsible for 80,000 deaths, the heart of the "Fat Man" atomic bomb was detonated on August 9, 1945, over the Japanese city of Nagasaki. Related: Iconic photos from WWII:
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be ...
A high explosive bomb is one that employs a process called "detonation" to rapidly go from an initially high energy molecule to a very low energy molecule. [18] Detonation is distinct from deflagration in that the chemical reaction propagates faster than the speed of sound (often many times faster) in an intense shock wave.
Several people are hurt and the superior courthouse in Santa Maria, California, is closed following “a bomb explosion” Wednesday morning, officials say.
