Mach wave Mach wave In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach waves are present at any location. Such a shock wave is called a Mach stem or Mach front. Thus, it is possible to have shockless compression or expansion in a supersonic flow by having the production of Mach waves sufficiently spaced ("cf." isentropic compression in supersonic flows). A Mach wave is the weak limit
Mach Rider on it. When the car is placed inside of it, it can be charged up and let loose at high speed. Later, "Mach Rider" was released as part of the "Nintendo Vs. Series" arcade variations. It was essentially a modified version of the Endurance Course from the original game. Each time the player completed a level, a bit more of an image was gradually revealed of a woman with a dagger appears next to Mach Rider's bike. While "Mach Rider" has not gained a true sequel, many elements from the game, such as the futuristic setting, incredible high speeds and
