MCQ
Light wave is travelling along $y -$ direction. If the corresponding $E$ vector at any time along the $x -$ axis, the direction of $B$ vector at that time is along.
- A$y -$ axis
- B$x -$ axis
- ✓$z -$ axis
- D$-z -$ axis
Light wave is an electromagnetic wave in which $E$ and $B$ are at right angles to each other as well as at right angles to the direction of wave propagation. So from the given information in the question, the direction of $B$ vector is in positive $z$ direction.
