One type of antenna can be made that is composed of two straight wires connected to an ac generator. Which one of the following statements concerning this type of antenna and electromagnetic waves is false? O When one of the wires has a net positive charge, the other wire has a net negative charge. O The generator continually injects electrons into the wires. O At each position far from the antenna, the amplitude of the electric and magnetic fields is the same. O As the potential difference at the terminals varies sinusoidally, electrons move between the ends of the wires. O The electric field and magnetic field vectors of the electromagnetic waves generated are perpendicular to each other when they are far from the antenna.
