8.Electromagnetic waves
easy

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

A

$y-$ axis

B

$x-$ axis

C

$+z -$ axis

D

$-\,z-$ axis

Solution

Light wave is an electromagnetic wave in which $\vec E$ and $\vec B$ are at right angles to each other as well as at right angles to the direction of wave propagation.
