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.
Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
