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.
What else can I help you with?
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Which is correct speed of light or velocity of light?
"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.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
Compared to the velocity of radio waves the velocity of visible light waves is?
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
Can phase velocity exceed the speed of light?
Yes, phase velocity can exceed the speed of light in certain mediums. This is known as superluminal phase velocity. However, this does not violate the principle of causality or the speed of light in vacuum as it is the group velocity, rather than the phase velocity, that carries the information in a wave.
What is the velocity of car light?
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.
what is the velocity of light?
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.
Do neutrinos travel at the speed of light, or do they move at a different velocity?
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
Which is correct speed of light or velocity of light?

Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
The velocity of light represents a cosmic speed?
The speed of light is basically the speed limit in the Universe.
What is the equation for relativistic mass in terms of velocity and the speed of light?
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.
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.
How fast can light travel up to?
c is a constant variable commonly known as "the speed of light", but more correctly the velocity of the speed of light ought to be called "the velocity of the speed of electromagnetic wave interactions". And it is precisely 299,792,458 meters per second.
Which factors affect the velocity of light?
The speed of light in a vacuum is constant. Otherwise, the speed of light will depend on what materials it travels through. For example, the speed of light in air is similar to the speed of light in a vacuum; in water, it is quite a bit slower.
