rs.This gives an average ratio for -j of 4.19, as determined by rierce.From his experiments and those of oonrad it may be concluded thatthe wave length produced by a Hertz rectilinear oscillator isvery approximately 4.2 times the length of one limb of the oscil-lator, provided this limb is greater than one meter long and ofcomparatively small diameter. -ust as electric waves produce different results when theyare traveling thru wires of different properties, so do they be-have differently when passing thru different parts of the earth,since the latter is composed of materials of different properties,such as different resistances and hence different conductivities.Thus, for example, sea water represents a gcod conducting materialfor wave lengths of about 600 meters long (the wave length gener-ally used in most calculations). Also the electric force is per-pendicular to the surface of the water. Oiagrams in Fig. 30 showthe different forms and directions that the waves will take, de- 31a
