Mile/hour
Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.
History/Origin
The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.
Current Use
Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.
Velocity Of Light In Vacuum
The velocity of light in vacuum, denoted by the symbol c, is the constant speed at which electromagnetic waves propagate through empty space, approximately 299,792,458 meters per second.
History/Origin
The concept of the speed of light has been studied since the 17th century, with significant contributions from scientists like Ole Rømer, who first estimated its finite speed in 1676, and Albert Michelson, who refined measurements in the late 19th and early 20th centuries. The value of c was precisely defined in 1983 by the International System of Units (SI).
Current Use
The speed of light in vacuum is a fundamental constant used in physics, astronomy, and engineering. It underpins theories of relativity, defines the meter in the SI system, and is essential for calculations involving electromagnetic radiation and high-speed phenomena.
