Question

Determine average value of poynting vector for a wave

Answer 1

Answer:

Explanation:

Direction of an Electromagnetic Wave. By definition, the direction of the Poynting vector must be mutually perpendicular to both the electric and magnetic fields. This relationship is expressed in terms of the cross product of the two fields: →S=1μ0→E×→B.

Answer 2

Explanation:

Poynting vector must be perpendicular to magnetic and electric field.
