  • C. A uniform plane wave is one in which x = 0 . and are perpendicular and lie in a plane For uniform pl and A uniform plane wave is one in which x = 0 . and are perpendicular and lie in a plane For uniform pl are perpendicular
  • D. A uniform plane wave is one in which x = 0 . and are perpendicular and lie in a plane For uniform pl and A uniform plane wave is one in which x = 0 . and are perpendicular and lie in a plane For uniform pl lie in a plane

  • Correct Answer
  • and lie in a plane 

    Explanation
    For uniform plane wave, E and H must be in a plane but perpendicular to each other.
