The equation is
v ≈ c
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
"Speed of light" is the correct term. Velocity refers to the speed of an object in a specific direction, while speed is the rate at which an object moves regardless of direction. The speed of light is approximately 299,792 kilometers per second in a vacuum.
E = energy e=mc2 (or Engergy (e) equals Mass (m) times the Velocity of Light (c) squared {the speed of light times itself}).
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Instantaneous.
The equation for relativistic mass in terms of velocity (v) and the speed of light (c) is: m m0 / (1 - v2/c2) where m is the relativistic mass, m0 is the rest mass, v is the velocity, and c is the speed of light.
Velocity is a vector quantity that includes both speed and direction. To convert speed to velocity, you need to include the direction in which the object is moving. So, the equation for converting speed to velocity is velocity = speed * direction, where direction is a unit vector indicating the object's direction of motion.
The equation mm0/ sqrt(1-v2/c2) is derived from Einstein's theory of special relativity. It describes how an object's mass (m) changes with its velocity (v) relative to the speed of light (c). The equation shows that as an object's velocity approaches the speed of light, its mass increases.
The speed of light in a vacuum is 300,000 kilometers per second - you don't need an equation for that. Two equations that involve the speed of light are: 1) Speed = wavelength x frequency (this equation applies to any wave, not just light) 2) Snell's law, which relates the speed of light in different substances with the substance's index of refraction. The equation for the speed of light is: c = (299,792,458 meters per second) divided by (refractive index of the medium) The refractive index of vacuum is precisely 1 .

The velocity of light in vacuum is 299,792,458km/s, for daily calculation it's considered as 300000km/s, so put the distance and "C"(velocity of light) in speed and distance equation and you will get the answer.[time=distance/speed]"atul ashish"
Which one SPEED? VELOCITY? ACCELERATION ?...
The word "black" aptly describes the inability of light to escape - all light and matter that passes the event horizon can only do so in one direction, falling in. The reason is, the escape velocity inside the event horizon is greater than the speed of light, the event horizon itself being the boundary at which the escape velocity is equal to that speed. Outside that horizon, the escape velocity is less than the speed of light, hence it would be possible for light and objects moving at speeds approaching that of light to escape.
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
The equation that shows how wavelength is related to velocity and frequency is: wavelength = velocity / frequency. This equation is derived from the wave equation, which states that the speed of a wave is equal to its frequency multiplied by its wavelength.
To determine the velocity of the approaching storm, you need to know both the speed at which the storm is moving (15 km/hr) and the direction in which it is moving. Velocity is a vector quantity, so it includes both the speed and the direction of motion.
