Lecher Lines K6 K6 ELECTROMAGNETIC OSCILLATIONS Two bare copper wires, 5 m long and 20 cm apart, are stretched above the lecture tables. The wires are connected at one end to a 4-meter RF oscillator (Å80 MHz) and are shorted at the other end. Small incandescent bulbs with rigid wires protruding from their terminals can be placed over the parallel wires and slid along them. Standing electromagnetic waves on the wires can be demonstrated by sliding the bulbs along the wires and finding the nodes and antinodes.
