Then the heat energy is converted into radi- ation and issues from the heated body, as for instance an incan- descent lamp filament, as a mass of radiations of different wave lengths, that is, different frequencies. All kinds of frequencies appear : from very low frequencies, that is only a few millions of millions of cycles per second, up to many times higher frequencies. We can get, if we desire, still very much lower fre- quencies, as electromagnetic waves, such ...

In the secondary or rotor of the induction machine, low-frequency currents — of the frequency of slip — are induced by the primary, but the magnetic field flux is produced by the exciting current which traverses the primary or armature or stator. Thus the induction machine may be considered as a machine in which the mag ...

NATURE AND DIFFERENT FORMS OF RADIATION. 1 The frequency of radiation follows from the velocity of light, and the wave length. The average wave length of visible radiation, or light, is about lw = 60 microcentimeters,* that is, 60 X 10~8 cm. (or about ^<y^<5-<y in.) and since the speed is S = 3 X 1010 cm. the ...

This is proportional to the frequency, and to the 1.6*'' power of the magnetic density, and is considerable, amounting in a closed magnetic circuit to 40 to 60 per cent, of the total volt-amperes.
