Answer:
The correct answer is B negative y-direction
Explanation:
An electromagnetic wave is created by the fluctuation of the electric and magnetic fields, which are perpendicular to each other, the direction of propagation is perpendicular to these two fields.
Let's apply the above to our problem, the wave propagates in the positive direction of the z-axis so that the electric and magnetic fields must be in the xy plane
They express that the electric field is in the negative direction of the x-axis, for the direction of the other field, we can make the vectoial product E x B with the result must be in positive z the only way is that the magnetic field (B) is in the negative direction of the y axis
The correct answer is B negative y-direction
