Question
Choose the correct answer from the alternatives given. Electromagnetic wave consists of periodically oscillating electric and magnetic vectors:

Answer

  1. In mutually perpendicular planes but vibrating in phase
Explanation:
The Electromagnetic wave consists of the two mutually perpendicular electric and magnetic fields present in the medium and also both being perpendicular to the direction of propagation of the wave. The two fields are in same phase as they obtain their peaks at the same instant.
An electromagnetic wave consists of periodically oscillating electric and the magnetic vector in mutually perpendicular planes but vibrating in phase.
