EM wave field vectors orientation – Rankers Physics

Properties of EM Waves: Practice Problem & Solution

In an electromagnetic wave, the oscillating electric and magnetic field vectors are oriented along
The direction of wave propagation
The same direction but perpendicular to wave propagation
Mutually perpendicular direction which is also perpendicular to direction of propagation
The same direction but at an angle of \(30^\circ\) to wave propagation

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of EM Waves. Understanding the underlying formula is key to arriving at the correct answer below:

In an electromagnetic wave, the electric field \(\vec{E}\), magnetic field \(\vec{B}\), and direction of wave propagation are mutually perpendicular to each other.
