The electric field of an electromagnetic wave in free space is given by \overrightarrow{E}=5 \sin (\frac{2 \pi}{3} z-\omega t) \hat{y} V \/ m . Which of the following statements is correct?

Correct Answer is : The wave vector is given →k=2π3∧z

The wave propagates along y^{\^}

The wave vector is given \overrightarrow{k}=\frac{2 \pi}{3} \hat{z}

The wavelength of the electromagnetic wave is \frac{1}{3} m

The corresponding magnetic field is \overrightarrow{B}=\frac{5}{c} \cos (\frac{2 \pi}{3} z-\omega t) \hat{x} T

The frequency of the wave is approximately 10^{6} Hz
