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.
Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffected by any gravity or other forces, it has some velocity (some speed in a given direction, or is moving at some distance per unit of time in a given direction), but it isn't changing speed or direction. If something is moving without changing its speed or its direction (either of which requires a force to act on the object - to accelerate the object), it has zero acceleration. Such an object is said to have a constant velocity and will have zero acceleration. Certainly if an object is not moving, it has zero velocity and zero acceleration, but that's probably not what is being asked. It has velocity (zero) and no acceleration. To recap, an object can have a non-zero velocity and zero acceleration.
The equation, as originally written by Erwin Schrodinger, does not use relativity. More complicated versions of his original equation, which do incorporate relativity, have been developed.For more information, please see the related link below.
Light waves are made up of electrical waves and magnetic waves that are perpendicular to each other and support each other, they are also perpendicular to the direction the waves are traveling so there are no vibrations in the direction the light travels.
Let's take these one-at-a-time ... -- Time doesn't 'stop'. If you shoot past Bob at high speed, and you and Bob look at each others' clocks as you pass, Bob will say that his clock is running normally and yours is running slow, while you will say that your clock is running normally and Bob's is running slow. You'll both be correct. If you were moving past Bob at the speed of light, Bob would say that his clock is OK and yours has stopped, while you would say that your clock is OK and Bob's has stopped. Again, you would both be correct. -- You don't reach the speed of light. -- Within a certain distance of a black hole, light can't escape. (That's why the region looks black from outside of it.) The light trapped in there is still moving at the speed of light. But nothing else in there is moving at the speed of light. This is not what I was asking and is incorrect (I edited my question for clarity). It is motion that is relative. Bob can claim you are moving or you can claim Bob is moving and both are correct. Time is different if you speed up you move through space faster thus you move through time slower. If you traveled at speeds near the speed of light for years when you returned to earth the people on earth would have aged more than you. Space and time are part of the same fabric. Once you reach the speed of light time stops because you are moving through space as fast as you possibly can thus there is no room for you to move through time. When it comes to the distortion of space time velocity and gravity are the same. If you are in a place with high gravity time slows down. So if you are in a black whole which has enough gravity to over power light which time stops at, does time go in reverse inside the black hole.
Recently an experiment at the CERN has clocked a Neutrino that they believe EXCEEDED the speed of light. They are double checking the results of this experiment, and looking for explanations.
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
moving toward light
Time recorded on the moving clock = (non-moving time) multiplied by the square root of (1 - v2/c2). v = the speed of the moving clock c = the speed of light
Photon or rather light
If you observe a clock moving past you at the speed of light, it will appear to you to have stopped.
This is not Spanish, this is the equation that describes the behavior of objects moving at speeds comparable with the speed of Light: E = M c2
We will land in past.when our speed is slower than light there will be some time in clock ,when our speed is same of light than the in click will stop for us, But when our speed is faster than light the clock will start moving reverse.
something very sciencey
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
the velocity of light is 300000000 m/s
The word "black" aptly describes the inability of light to escape - all light and matter that passes the event horizon can only do so in one direction, falling in. The reason is, the escape velocity inside the event horizon is greater than the speed of light, the event horizon itself being the boundary at which the escape velocity is equal to that speed. Outside that horizon, the escape velocity is less than the speed of light, hence it would be possible for light and objects moving at speeds approaching that of light to escape.
