It is my understand that there is not anything that can travel faster than the speed of light. Perhaps ones thoughts are faster though I am not sure on that point.
Robert Tachyons are theoretical particles that will cease to exist if they slow down to light speed.
No.
No known particles can travel faster than the speed of light in a vacuum, according to the theory of special relativity. In a medium like water, particles such as neutrinos can travel faster than the speed of light in that medium, but not in a vacuum. In solids, sound waves can propagate faster than light as well.
no it is notans2. It is important to specify the medium in which the phenomenon is acting. There is a prohibition on anything travelling faster than the speed of light in vacuo.However this restriction is side-stepped in a medium in which light travels slower than in vacuo. Cherenkov radiationis one such example, where energetic particles travel faster in the medium (in this case usually water) than light would do.Cherenkov's observations date to the 1930s.
Violet light is faster than red light because violet light has a shorter wavelength and higher frequency, allowing it to travel faster through a medium.
Nothing is faster than the speed of light in a vacuum (other household appliances are left as an exercise for the reader). Electricity travels at essentially the speed of light in the conductive medium it's traveling through, but not faster.
True, the speed of light is faster in a transparent medium like water or glass compared to its speed in a vacuum. This difference in speed is due to the different refractive indexes of the medium, which affects the speed at which light travels through it.
Light is faster than magnetism. The speed of light in a vacuum is constant at approximately 186,282 miles per second (299,792 kilometers per second), while the speed of magnetic fields propagating through a medium is usually much slower.
Light travels faster in air compared to glass because the speed of light is inversely proportional to the refractive index of the medium. Air has a lower refractive index than glass, so light can move faster through air than through glass.
Light travels slower through denser media, so it travels faster through water than through a diamond.
neutrinos
The speed of a light wave can be changed by traveling through different mediums with varying refractive indexes. When light enters a medium with a higher refractive index, it slows down, and when it exits to a medium with a lower refractive index, it speeds up. This change in speed is due to the interaction of light with the atoms in the medium.
Light travels faster in a vacuum than in any other medium, such as air or water. Its speed in a vacuum is approximately 186,282 miles per second (299,792 kilometers per second).
