Question 22 of 165

A plane electromagnetic wave propagates along the $+x$ direction in free space. The components of the electric field, $\vec{E}$ and magnetic field, $\vec{B}$ vectors associated with the wave in Cartesian frame are

A$\mathrm{E}_x, \mathrm{~B}_y$B$\mathrm{E}_y, \mathrm{~B}_z$C$\mathrm{E}_z, \mathrm{~B}_y$D$\mathrm{E}_y, \mathrm{~B}_x$

Show answer and solution▾

Answer: (B) $\mathrm{E}_y, \mathrm{~B}_z$

Direction of propagation
$=\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}$
