NEET 2018 Physics Properties of EM Waves MCQ Question
Type: MCQ-conceptual-Medium-Class 12
An em wave is propagating in a medium with a velocity v⃗ = vî. The instantaneous oscillating electric field of this em wave is along +Y axis. Then the direction of oscillating magnetic field of the em wave will be along
A
−Z direction
B
+Z direction
C
−Y direction
D
−X direction
Correct Answer
Option B
Detailed Explanation
The direction of the magnetic field is given by the right-hand rule. If the electric field is along +Y and the wave propagates along +X, the magnetic field is along +Z.
