This is different from the rate at which the wavefront propagates through the medium. The wave itself, you can consider to be a disturbance in/of the electromagnetic field. These are not concepts that lend themselves very well to tangible analogies when studied in depth.

Jul 1, 2016 at 21:55 comment added user3921 Hey, thank you for youre great comment. So let me just get things straight. When i read about a digital communication signal x(t) = cos(Wc*t). This "thing" travels at the speed of light regardless of Wc, So what is this Wc frequency in a physical manner? What do i do in order to transmit at Wc or at other frequency Wf?

Let's not use "in a vacuum" idiomatically while discussion wave propagation speed, mmkay
