JEE Main 2025 — 29 January, Evening Shift — Question 24

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 :

Option A:
$E_{y}, B_{x}$
Option B:
$E_{y}, B_{z}$
Correct
Option C:
) $E_{x}, B_{y}$
Option D:
$\mathrm{E}_{z}, \mathrm{~B}_{y}$

Answer: B

Step-by-step solution

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