Question

Light wave is travelling along $y$ -direction. If the corresponding E vector at any time is along the $x$ -axis, the direction of B vector at that time is along

$y$ -axis
$x$ - axis
$+ z$ - axis
$- z$ - axis

The correct answer is: $plus z$ - axis

The given wave in an Electromagnetic Waves. Electromagnetic radiation is a self propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.

Hence, B is along the $z$ -axis at that time.
