It is known that the electric field component of the EM wave is given by
[itex]E=E_{0}cos(kx-\omega t)[/itex]
How do I arrive at such a form?
It is quite different from the standard sinusoidal equation of [itex]y=Acos(\omega t+\varphi)[/itex]
Any guidance?
What does the [itex]kx-\omega t[/itex] describe physically?
