Question Section 5: Navigation 69 Answer 11

Radio theory an electromagnetic wave has two types of energy field An e electrical field h magnetic field, an h electrical field an e magnetic field, a z electrical field an h magnetic field, a z magnetic field an e electrical field.
Question Section 5: Navigation 69 Answer 12

Radio theory an electromagnetic wave consists of an oscillating electric field e and an oscillating magnetic field h which statement correct The (e) (h) fields are perpendicular to each other, a dipole antenna can only transmit field (h), the (h) field parallel to wire field (e) perpendicular to wire, when ac current pass through antenna, fields (e) (h) are parallel.
