3) Calculations:
a) From the given equation, the term ‘kz’ denotes that the wave is travelling along z direction. And the sign indicates that the wave is travelling along the positive z axis.
b) As the magnetic field is oscillating parallel to y axis and the wave is traveling along z direction. The electric field must oscillate parallel to x-axis, perpendicular to both, the direction of the propagation of wave and the magnetic field.
Conclusion:
Using the information of the given equation, we can indicate the direction of the wave and its electric and the magnetic field components.
