- Let E be the effective elasticity of the aether; then E = pc t, where p is its density, and c the velocity of light which is 3 X 10 10 cm./sec. If = A cos" (t - x/c) is the linear vibration, the stress is E dE/dx; and the total energy, which is twice the kinetic energy Zp(d/
**dt**) 2 dx, is 2pn2A2 per cm., which is thus equal to 1.8 ergs as above. - A dielectric substance is electrically polarized by a field of electric force, the atomic poles being made up of the displaced positive and negative intrinsic charges in the atom: the polarization per unit volume (f',g',h') may be defined on the analogy of magnetism, and d/
**dt**(f',g',h') thus constitutes true electric current of polarization, i.e. - These circuital relations, when expressed analytically, are then for a dielectric medium of types = (
