299,792,458 meters (186,282 miles) per second
The speed of a photon in a vacuum is approximately 299,792 kilometers per second, which is the fastest speed possible in the universe.
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
The speed of gamma radiation in air or vacuum is approximately the speed of light, which is about 299,792,458 meters per second.
The fastest possible speed that an object can travel in a vacuum is the speed of light, which is approximately 299,792 kilometers per second.
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)
About 2/3 its speed in a vacuum.
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
In vacuum, the speed is 299,792,458 meters per second.
Light is fastest in a vacuum; in this case, its speed is about 300,000,000 meters/second.Light is fastest in a vacuum; in this case, its speed is about 300,000,000 meters/second.Light is fastest in a vacuum; in this case, its speed is about 300,000,000 meters/second.Light is fastest in a vacuum; in this case, its speed is about 300,000,000 meters/second.
No it won't because it is vacuum sealed
The speed of X-rays in a vacuum is the same as the speed of microwaves in a vacuum, as both travel at the speed of light, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This is true for all forms of electromagnetic radiation in a vacuum, regardless of their frequency or wavelength. Therefore, there is no difference in speed between X-rays and microwaves when in a vacuum.
The speed of a photon in a vacuum is approximately 299,792 kilometers per second, which is the fastest speed possible in the universe.
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
Air pressure from outside and vacuum effect from inside.
The speed of an electron in a vacuum is approximately 2.2 million meters per second.
The speed of electrons in a vacuum is approximately 2.2 million meters per second.
Speed. All photons traveling through a vacuum travel at the speed of light.
