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.

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 ...

Iridescent colors, for instance, are those of mother-of-pearl, of opal, of many butterflies, etc. Light, therefore, is a wave motion. 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 ...

In the following, mainly the light waves, that is, the second or high frequency range of radiation, will be discussed. The elec- tric waves are usually of importance only in their relation to the radiator or oscillator which produces them, or to the receiver on which they impinge, and thus are treated in connection with the radiator ...

It has practically gone out of use for standard frequencies, due to its lower economy in the use of materials, but has remained a very important type of construc- tion, as it is especially adapted for high frequencies and other special conditions, and in this field, its use is rapidly increasing.

In the alternating magnetic field, power is consumed by mag- netic hysteresis. 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. In the dielectric field, the energy losses usually are very much smaller, rarely amounting to ...
