The electric field associated with an electromagnetic wave travelling in vacuum is given by
\[
\vec E
=
E_0\sin(3y+4z+\omega t)\,\hat i
\]
where \(\omega\) is the angular frequency. All quantities are in SI units. The correct statement(s) about this wave is/are:
\[
[\text{Given: speed of light in vacuum }c=3\times10^8\ \text{m s}^{-1}]
\]
