A shock wave is a type of propagating disturbance. When a wave moves faster than the speed of sound in a liquid, gas or plasma (a fluid, in physics terminology) it is a shock wave.
The shock wave extends outward for the first 30 feet (10 m), after which it becomes an ordinary sound wave called thunder. The speed of sound through air at sea level is 758 mph (1,130 feet/second; 344 m/second) at 68Â° F (20Â° C). Thunder is exploding air occurring along the entire length of the lightning channel.
