Physics · Displacement current, electromagnetic waves and their characteristics, transverse nature of electromagnetic waves
An electromagnetic wave has energy in the form of
An electromagnetic wave has energy in the form of
- A. variable electric field
- B. variable magnetic field
- C. both A and B
- D. none of the above
Step-by-step solution
Electromagnetic waves consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. The energy of the wave is stored in these fields, which vary in time and space. Thus, the energy is in the form of both variable electric and variable magnetic fields.
