      "text": "Polarization refers to the direction of travel of an electromagnetic wave vector’s tip: vertical (up and down), horizontal (left to right), or circular (rotating in a constant plane left or right). The direction of polarization is defined by the orientation of the wave’s electric field, which is always 90°, or perpendicular, to its magnetic field.",
