Ernst Mach of experimental physics concentrated on the interference, diffraction, polarization and refraction of light in different media under external influences. From there followed important explorations in the field of supersonic fluid mechanics. Mach and physicist-photographer Peter Salcher presented their paper on this subject in 1887; it correctly describes the sound effects observed during the supersonic motion of a projectile. They deduced and experimentally confirmed the existence of a shock wave of conical shape, with the projectile at the apex. The ratio of the speed of a fluid to the local speed of sound "v"/"v" is now called the Mach number. It
Mach Five his crew, and with other racers. Functions are not activated by a steering wheel hub lettered A-G, but instead, by switches mounted around the steering wheel. The Mach 6 succeeded the Mach 5 as the main vehicle for the rest of the series. More of the original gadgets were gradually revealed (such as the sludge slick) and used in future episodes. Eventually, the Mach 5 returned as Speed Racer Sr.'s main car in the season 2 premiere. Mach Five The is the racing car Speed Racer (Go Mifune in the Japanese version) drives in the anime series of the same
