Question

The electric and magnetic fields of an electromagnetic wave are:

• A. perpendicular to each other
• B. parallel to each other
• C. 45° oblique each other
• D. 30° oblique each other

Hint:

EM wave = E ⟂ B ⟂ direction of propagation.

Answer 1

The Correct Option is A

In an electromagnetic wave, the electric field (E), magnetic field (B), and the direction of propagation (k) are mutually perpendicular. This orthogonal nature defines the transverse wave property of EM waves.
