An electromagnetic wave has an electric field given by

E$($y$,$t$)=[2\mathrm{.}80105$V$/$mcos$($ky$(1\mathrm{.}0451013$rad$/$s$)$t$)]$k$^$E$($y$,$t$)=[2\mathrm{.}80105$V$/$mcos$($ky$(1\mathrm{.}0451013$rad$/$s$)$t$)]$k$^.$ In which direction is the wave traveling? What is the wavelength of the wave?
