Yes it can, because the phase velocity of a matter wave does not carry information, and thus does not violate special relativity. The group velocity is what is limited by c.
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.
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group velocity.
"Speed of light" is the correct term. Velocity refers to the speed of an object in a specific direction, while speed is the rate at which an object moves regardless of direction. The speed of light is approximately 299,792 kilometers per second in a vacuum.
No, according to the theory of relativity, it is impossible for any particle with mass to reach or exceed the speed of light. Accelerators can increase the speed of particles to high fractions of the speed of light, but they cannot exceed it.
Instantaneous.
Group velocity is the speed at which the envelope of a wave packet propagates, carrying energy and information. Phase velocity is the speed at which the individual wave crests propagate. In some cases, the group velocity can exceed the phase velocity, such as in the case of dispersive media.
Phase velocity is the speed at which the phase of a wave propagates through a medium. It is the rate at which the phase of a wave changes with respect to time or distance. Phase velocity is different from group velocity, which describes how the overall shape of a wave packet moves.
Guide wavelength is defined as the distance between two equal phase planes along the waveguide. The guide wavelength is a function of operating wavelength (or frequency) and the lower cutoff wavelength, and is always longer than the wavelength would be in free-space. Here's the equation for guide wavelength:Guide wavelength is used when you design distributed structures in waveguide. For example, if you are making a PIN diode switch with two shunt diodes spaces 3/4 wavelength apart, use the 3/4 of a guide wavelength in your design. The guide wavelength in waveguide is longer than wavelength in free space. This isn't intuitive, it seems like the dielectric constant in waveguide must be less than unity for this to happen... don't think about this too hard you will get a headache. === ===
You can't .
Phase velocity refers to the speed at which the phase of a wave propagates through space, while group velocity refers to the speed at which the envelope of the wave (group of wave packets) propagates through space. In many situations, the phase velocity can be different from the group velocity, leading to phenomena like dispersion.

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.
energy. As a particle's speed approaches the speed of light, its energy increases, but it cannot exceed a certain value. This limit is known as the speed of light, and particles with mass cannot travel at or beyond this speed.

Nothing can exceed the speed of light - Einstein called it the "cosmic speed limit".
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
