The expression for an electric field in free space is  , where x, y, z represent the spatial coordinates, t represents time, and ω,k are constants. This electric field 
  • a)
    does not represent a plane wave
  • b)
    represents a circular polarized plane wave propagating normal to the z-axis
  • c)
    represents an elliptically polarized plane wave propagating along x-y plane.
  • d)
    represents a linearly polarized plane wave
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The expression for an electric field in free space is ,where x, y, z r...

The dot product between above two is = 1 - 1 + 0 = 0
⇒ It is a plane wave
We observed that
 are normal to each other.
So electric field can be resolved into two normal component along 
The magnitude are 
So elliptical polarization.
