How fast is light travel
WebFaster Than Light Travel is Possible. Faster Than Light Travel is one of the mechanisms used in science fiction for fast interstellar travel, where spacecraft move from one point to another distant point in a relatively short time. However, in current physics, any form of … WebSince the velocity of propagation is very high – about 300,000 kilometers per second – the wave of an alternating or oscillating current, even of high frequency, is of considerable length. At 60 cycles per second, the wavelength is 5,000 kilometers, and even at 100,000 hertz, the wavelength is 3 kilometers.
