What is Speed of Light?
Speed of Light (c) is a unit of speed. The speed of light in vacuum is exactly 299,792,458 meters per second by definition, serving as a fundamental constant in physics and the SI system [bipm-si-brochure]. It links space and time units and defines the meter. This constant underpins electromagnetic theory and relativity. The speed of light was fixed by the 1983 CGPM resolution to define the meter precisely in terms of the distance light travels in vacuum in 1/299,792,458 seconds [cgpm-resolutions]. This replaced earlier measurement-based definitions. The speed of light is a universal constant used globally in physics, engineering, telecommunications, and astronomy. It forms the basis for defining the meter and plays a key role in GPS and high-speed data transmission standards [bipm-si-brochure].
What is First Cosmic Velocity?
First Cosmic Velocity (v1) is a unit of speed. The first cosmic velocity is the minimum orbital speed required for an object to maintain a stable circular orbit just above a planet's surface, approximately 7.9 km/s for Earth. It is derived from Newtonian mechanics and gravitational parameters, calculated by √(GM/R) where G is the gravitational constant, M the planet mass, and R its radius [nist-cuu]. The concept of cosmic velocities was formulated by Russian scientist Konstantin Tsiolkovsky in the early 20th century when studying orbital mechanics. It formalized escape and orbital speeds as fundamental limits for spacecraft [nist-cuu]. This velocity is critical in aerospace engineering and space mission design globally, used by space agencies such as NASA, ESA, and Roscosmos. It serves as a baseline for launching satellites into low Earth orbit [nist-cuu].
Common Misspellings
People often search for this conversion using these alternate spellings: speed of lite, speed of lightt, speed-of-light, speedoflight, spead of light, first cosmic velocity, cosmic velocity 1st, cosmic velocity one, orbital velocity first, cosmic velocity 1. All of these refer to the Speed of Light to First Cosmic Velocity conversion.
