The electric field associated with an electromagnetic wave travelling in vacuum is given by \( E_{0}\sin(3y + 4z + \omega t)\,\hat{i} \), where \( \omega \) is the angular frequency. All quantities are in SI units. The correct statement(s) about this wave is/are: [Given: speed of light in vacuum \( c = 3 \times 10^{8} \, \mathrm{ms^{-1}} \) .]
