Question

If $\vec{E}$ and $\vec{B}$ represent the electric field vector and magnetic field vector, respectively, in an electromagnetic wave then the direction of EM wave is along:

Accepted Answer

1. **Transverse Nature:** Electromagnetic waves are transverse in nature. The electric field ($\vec{E}$) and magnetic field ($\vec{B}$) oscillate perpendicular to each other and perpendicular to the direction of wave propagation.
2. **Direction of Propagation:** The direction of propagation of an electromagnetic wave is given by the direction of the Poynting vector, which is defined as $\vec{S} = \frac{1}{\mu_0} (\vec{E} 	imes \vec{B})$. Therefore, the wave propagates along the vector product $\vec{E} 	imes \vec{B}$.
