Blast Effects Due to Reflected Shock Waves

Blast waves are reflected from solid surfaces but not in the same manner as sound and light waves are reflected. When a bomb is detonated at some distance above the ground, the shock wave spreads out almost spherically until it strikes the ground. This initial wave, called the incident wave, is reflected by the ground surface. At a certain distance along the ground, from the point immediately below the bomb, the reflected wave combines with the original or incident wave to form a third wave...
