The speed of all types of electromagnetic radiation, including light,
in vacuum, is:
-- 299,792,458 meters per second
-- 186,282 miles per second.
In material media, such as air or water, it's slightly less, and depends
on the substance.

∙ 10y agoThe speed of light in a vacuum is the same for any color of visible light... as well as invisible light such as ultraviolet light or x-rays. This speed is 300,000 km/second.

∙ 10y agoThe speed of light is 299,792,458 meters (that's 186,282.397 miles) per second
in vacuum, and somewhat less in any material substance.

∙ 11y ago299,792,458 meters per second is the proper measurement for the speed of light.
However, Americans would say 186,000 miles per second, which is about accurate.

What is the value of orbital velocity?
the approximate value of orbital velocity is about 8km/hr.
What properties of space determine the velocity of light?
The velocity of light and all electromagnetic radiation is determined by two properties of space. One is the electrical property which is permittivity and the other is the magnetic property which is permeability. Their values were determined more than 150 years ago by the great scientist Jame Clerk Maxwell. They are not constant in value, but vary based on the material in which they are located. In most cases they diminish the velocity, but in a few they increase it. If the value of either or both of these properties can be modified, then the velocity of light can also be modified.
Would instantaneous velocity yield the same value as average velocity?
Only if the velocity is constant.
The velocity of light is 3.00 which is equal to what?
This question does not make sense. Part (1) "The velocity of light is 3.00" is a statement within the question following Part (2) "which is equal" is again a statement. Part (3) "to what?" is the question. So if I ask, "The velocity to what?" and replace the word "velocity" with "light" to define it better, I get, "The light to what?" and substitute the value of light with the given in Part (1) and add the second statement given in Part (2), I get, "3.00 is equal to what?" Hello? is what I want to ask. Perhaps reversing the original question will enlighten: "What is equal to the velocity of light...which is 3.00?" Wa-la. This was a trick question. The answer in not only within the question itself, but also happens to correlate to the number of minutes wasted answering this...this...
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.
What are some of ancient India's inventions?
velocity of light,pi value
Is it possible for something to have an escape velocity equal to light?
No light is the fastest possible. Nothing escapes the velocity of light. ==================================== Sure. The escape velocity at some appropriate distance from a black hole is equal to 'c'. That's why the hole is black. The exact value of the distance depends on the hole's mass.
What is dependent value in velocity time graphs?
The dependent value on a velocity-time graph is velocity.
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
What is the value of orbital velocity?
the approximate value of orbital velocity is about 8km/hr.

Does Light have a speed or a velocity speed of light or velocity of light?
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 would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?
As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................
Is the velocity of a red light lower than the velocity of violet light?
No it justs refracts further
Is the velocity of a red light lower than the velocity of violet light a?
Not necessarily, but the frequencies are different.
Would instantaneous velocity yield the same value as average velocity?
Only if the velocity is constant.
Why is the value of velocity equal to speed?
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
