Understanding Mach and Speed of Light
What is Mach Number?
Mach number (M) represents the ratio of an object's speed to the speed of sound in the surrounding medium. At sea level and standard atmospheric conditions, Mach 1 equals approximately 767.269 mph (1,234.8 km/h).
| Classification | Mach Range |
|---|---|
| Subsonic | Mach < 1.0 |
| Transonic | Mach = 1.0 |
| Supersonic | Mach > 1.0 |
Speed of Light (c)
The speed of light in vacuum, denoted by 'c', is a fundamental physical constant. It equals exactly 299,792,458 meters per second. This speed represents the upper limit for the motion of all matter and information in the universe.
