Identify the correct statements from the following descriptions of various properties of electromagnetic waves. A. In a plane electromagnetic wave electric field and magnetic field must be perpendicular to each other and direction of propagation of wave should be along electric field or magnetic field. B. The energy in electromagnetic wave is divided equally between electric and magnetic fields. C. Both electric fiel

Options

  1. AD only
  2. BB and D only
  3. CB, C and E only
  4. DA, B and E only

Correct answer

B. B and D only

Step-by-step solution

In an electromagnetic wave electric field magnetic field and the direction of propagation of the wave are mutually perpendicular. Therefore, statement D is correct and statement A and C are incorrect. The energy is equally divided between electric and magnetic field. Therefore, statement B is correct. Speed of light c = E 0 B 0 . Therefore, statement E is incorrect.
