capacity may be calculated from its dimensions, and by photo- 22 graphing the spark in order to obtain the period and from that thewave-length. In the last two instances the wave-length is obtain-ed by the application of Lord Kelvin*s formula. For wave-lengths up to 200 meters, the parallel-wire… … Fig. 24. It consists of a Hertz oscillator whose end capacities are metalplates about 30 cm. square, opposite which two similar plates arei placed to form the air condensers and Cg. Two wires, a and c,attached to these outer plates are brought parallel to each otherand about 10 cm. apart and…
