Question

How are electric vector $\overrightarrow{\left(E\right)}$, magnetic vector $\overrightarrow{\left(B\right)}$ velocity vector $\overrightarrow{\left(c\right)}$ oriented in an electromagnetic wave ?

Answer 1

According to the Fleming's right hand rule, the electric vector $\overrightarrow{\left(E\right)}$, the magnetic vector $\overrightarrow{\left(B\right)}$ and the velocity vector $\overrightarrow{c}$ are mutually perpendicular to each other.
