Electromagnetic Waves

The wave is travelling in $-\frac{1}{5} (3 \hat{j} + 4 \hat{k})$ direction.

The magnitude of the wave vector is $0.5\ \mathrm{m}^{-1}$.

The value of $\omega$ is $1.5 \times 10^9 \ \mathrm{rad}\ \mathrm{s}^{-1}$.

The magnetic field associated with this wave is given by $\frac{E_0}{c} \sin(3y + 4z + \omega t)(4 \hat{j} - 3 \hat{k})$.
