NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Imagine a diagram showing a plane electromagnetic wave propagating along the x-axis with the electric field vector E along the y-axis. Which direction does the magnetic field vector B point?
A
Along the z-axis.
B
Opposite to the x-axis.
C
Along the y-axis.
D
Opposite to the z-axis.
Correct Answer
Option A
Detailed Explanation
For a plane electromagnetic wave propagating in the x-direction, the electric field E is along the y-axis, and the magnetic field B is perpendicular to both E and the direction of propagation (x-axis), hence along the z-axis.
