Type: MCQ-conceptual-Medium-Class 12
A plane electromagnetic wave propagating along x direction can have the following pairs of E and B.
A
Eᵧ, B_z
B
E_z, Bᵧ
C
Eₓ, Bᵧ
D
Both (a) and (b)
Correct Answer
Option D
Detailed Explanation
As electric and magnetic field vectors E and B are perpendicular to each other as well as perpendicular to the direction of propagation of electromagnetic wave. Eᵧ × B_z = vₓ, similarly E_z × Bᵧ = -vₓ.
