NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram where a plane electromagnetic wave is traveling along the x-axis with electric field E oriented along the y-axis. What is the direction of the magnetic field B in this wave?
A
Along the z-axis
B
Along the x-axis
C
Opposite to the y-axis
D
Opposite to the z-axis
Correct Answer
Option A
Detailed Explanation
In a plane electromagnetic wave, the magnetic field B is perpendicular to both the direction of wave propagation and the electric field E. Since E is along the y-axis and the wave travels along the x-axis, B is along the z-axis.
