Traffic waves travel backwards relative to the cars themselves. [1] Relative to a fixed spot on the road the wave can move with, or against the traffic, or even be stationary (when the wave moves away from the traffic with exactly the same speed as the traffic). Traffic waves are a type of traffic jam.
Observers hear nothing until the shock wave, on the edges of the cone, crosses their location. Mach cone angle NASA data showing N-wave signature. [1] Conical shockwave with its hyperbola-shaped ground contact zone in yellow. A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed ...
The Boston tunnel was filled with 130,000 gallons of stormwater runoff this week after a torrential downpour led officials to close the historic city's roadways.

In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...
By MORGAN WHITAKER New video has emerged of the impressive sights and sounds spectators experienced as they watched Tuesday evening's disastrous launch of a NASA contractor's unmanned Antares rocket.
Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough.
Passengers in the 35-second video react in disbelief as they watch the two planes slowly get closer to each other, collide and then halt with no visible major damage. “It hit the other plane.
