The Mach number is a dimensionless quantity used to represent the speed of an object relative to the speed of sound in a particular medium. It is named after the Austrian physicist and philosopher Ernst Mach. The Mach number is calculated by dividing the velocity of the object by the speed of sound in the same medium, and it provides a measure of how fast an object is moving compared to the speed at which sound waves travel through that medium. For example, a Mach number of 1 indicates that an object is traveling at the speed of sound, while a Mach number greater than 1 indicates supersonic speeds, and a Mach number less than 1 represents subsonic speeds
