In a vacuum, light travels at a constat speed. It won't get faster or slower over time.

In other substances (e.g., in water) light moves at a speed determined by the characteristics of the substance. Here, it won't get slower or faster with time, either.

Can you move faster than electricity?

No, electricity moves at the speed of light, which is the fastest speed possible in the universe. Therefore, it is not possible for anything to move faster than electricity.


Why does light travel faster through empty space than matter?

Light travels faster through empty space because there are no particles for it to interact with, whereas in matter, light is constantly being absorbed and re-emitted by particles, slowing it down. In a vacuum, light moves at its maximum speed of about 299,792 kilometers per second.


What happens to light as it moves at an angle into a medium that has a lower index of refraction?

Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.


Would light travel faster through space or wind?

It would travel faster through space since there are no particles to get in its way. The wind is an opposing force so it is harder to move faster. The difference between the two would be negligble but specifically, light moves faster through space.


What is mass of a particle when it moves with velocity of light?

Fasten your seat belt . . .-- If the particle has any mass when it's not moving, then that mass becomes greaterthe faster the particle moves.-- If the particle could be pushed to the speed of light, its mass would be infinite at that speed.-- But in order to make the particle move faster, you have to add energy to it. The more mass it has,the more energy you have to give it in order to make it move faster.-- Since its mass grows as it moves faster, the amount of energy it takes to make itgo faster also grows.-- If its mass is growing toward infinity, then the amount of energy you need to make itgo faster is also growing toward infinity.-- Since the mass would be infinite at the speed of light, you would need an infinite amountof energy to boost it to that speed.-- You don't have enough energy available to do the job, and you can''t get it.

It is not. Nothing that we are aware of moves faster than light.


Why is the light blurrer as light moves further?

Light is bluer as it moves farther is because blue travels faster than the other colors in the visible spectrum.


What happens to the mass of a particle as the particle approacches the speed of light?

When any object with mass moves, no matter at what speed, its mass increases. The faster it moves, the faster its mass increases. And the closer to the speed of light it moves, the closer to infinity its mass grows.


If someone moves faster than light does it become dark?

It is impossible to move faster than light, as your mass increases as your speed approaches that of light. The Speed of Light would mean infinite mass, which it is impossible to make faster.


Does light move faster in oil or water?

Light moves faster in Water due to the lighter density...Also due to the fact that Oil is darker in color whereas Water allows light through...


What creates light waves?

The wind and the temperature of the water makes it move, and the heavier it is the faster it moves.


How much faster is the speed of light than the speed of electricity without using superconducting materials eg in normal computers?

We generally consider that the force of an electric field moves at the speed of light. And electricity moves at the speed of light.

What is meant by tachyons?

A tachyon is a hypothetical subatomic particle that moves faster than light and is incapable of moving slower than the speed of light.


What do you call something that is faster than the speed of light?

Something that moves faster than the speed of light is considered to be traveling superluminally. However, according to our current understanding of physics, nothing with mass can travel faster than the speed of light in a vacuum.


Why the flash of the gun reaches as before the sound of the gun?
