Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
At approx 300,000,000 metres per second.
It is currently not possible to travel at the speed of light according to our current understanding of physics. Developing technology to allow for light speed travel would require major breakthroughs in propulsion systems, energy sources, and materials. While advancements continue to be made in space exploration, it is uncertain if such technology will be achievable in our lifetime.
Yes, it is theorized that there are higher dimensions then the four we are familiar with. No, you cannot travel at the speed of light, no physical object that has mass can. However, that being said, you can, theoretically travel infinitely close to the speed of light which would, in turn, require an infinite amount of energy.
Through a vacuum ... yes. Through outer space, which is not quite a vacuum ... not quite, but very very close.
An RF signal travels at the speed of light in space, which is approximately 299,792 kilometers per second. This means that RF signals travel at the same speed as light in a vacuum.
Light waves in space travel at about 186,282 miles per second or approximately 300,000 kilometers per second. This speed is constant and is known as the speed of light in a vacuum.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.

I assume you mean electromagnetic waves. In outer space, they will travel at the speed of light (since light is also an electrodynamic wave). This speed is about 300,000 kilometers per second.
Nothing can travel at the speed of light, only light itself, the closest we have ever gotten to the speed of light is 99.9 %, we have accelerated particles at very very close to the speed of light using the LHC (Large Hadron Collider). The only thing that can go faster than the speed of light, is Space.
Gravitational waves travel through space at the speed of light, which is about 186,282 miles per second.
At approx 300,000,000 metres per second.
by converting one into light particles.
All colors of light travel at the same speed in space, which is the speed of light in a vacuum, approximately 299,792 kilometers per second. This constant speed of light is a fundamental principle in physics, as described by Einstein's theory of relativity.
