The direction of propagation of an electromagnetic wave is given by
A) $\vec { E } \cdot \vec { B }$
B) $- \vec { E } \cdot \vec { B }$
C) $\vec { E } \times \vec { B }$
D) $\vec { B } \times \vec { E }$

Question

Quizplus · Accepted Answer

The direction of propagation of an electromagnetic wave is given by the cross product $\vec { E } \times \vec { B }$, where $\vec { E }$ is the electric field vector and $\vec { B }$ is the magnetic field vector. This follows from the right-hand rule for cross products.
