Chapter 15: Problem 2177

What oscillates in an electromagnetic wave? (A) \(\mathrm{E}^{-}\) and \(\mathrm{B}^{-}\) (B) \(\mathrm{B}^{-}\) (C) \(E^{-}\) (D) none of these

Short Answer

Expert verified
The correct answer is (A) \(\mathrm{E}^{-}\) and \(\mathrm{B}^{-}\), as both the electric (E) and magnetic (B) fields oscillate in an electromagnetic wave.

Step by step solution

01

Properties of Electromagnetic Waves

Electromagnetic waves are formed by the interaction of electric (E) and magnetic (B) fields that are perpendicular to each other and to the direction of wave propagation. These fields oscillate as the wave moves through space or a medium. For example, in a propagating wave with its electric field oscillating in the vertical direction, the magnetic field will oscillate in the horizontal direction. Step 2: Identifying oscillating components
02

Electric and Magnetic Field Oscillation

In an electromagnetic wave, both the electric (E) and magnetic (B) fields oscillate. As the electric field fluctuates, it creates a changing magnetic field, which in turn generates a changing electric field. This continuous interchange of energy between the electric and magnetic fields allows the electromagnetic wave to propagate. Based on this analysis, the correct answer is: (A) \(\mathrm{E}^{-}\) and \(\mathrm{B}^{-}\)
