Suppose a station was transmitting on a wavelength of JfcV meter. The frequency would he approxiof the carrier-wav- e mately 833,000 cycle. Just a a violinist tunes his Instrument, that Is. makes a certain string emit a note of higher or lower pitch, or. technically shaking, a sound wave of higher or lower frequency, by adjusting the tensing m me string, so may the electrical constants of tlie antenna circuit of a radiophone transmitter be changed in order to have of a the station emit a carrier-wav- e different frequency. If n tuning fork having n natural period corresponding to middle C be placed near a violinist who Is playing, the fork will vibrate when the musician play middle C. but all other time it will remain quieaceut. This phenomenon of tha tunlug fork vibrating whenever the musician plays the corresponding note on the violin Is known as mechanical resonance. If a radio receiver be adjusted so that electrically Its natural period of vibration will be 5! 835,0110 cycles (300 meters wave- - j length) every time n station transmits . on n wave-lengtof 800 meters, cur- rent will be set up In the receiver by elevtrirol resonance, Station trann- other than mittlng on any wave-lengtS00 meters will not cause a current , to he set up In the receiver. j The portion of a radio receiver that at which it changes the wave-lengtis electrically resonant Is called a tuner. Suppose that A station transof 200 meters mits on a wave-lengtof 300 meand "If on a wave-lengt- h ters. By adjusting the tuner until the constants of the receiver make It elecwave trically resonant to a r or a wave, either of the two stations can he picked up, but both stations cannot lie picked up simultaneously. This is the reason that more than one transmitter can lie operating at one time and yet only one can. be heard on s receiver without Interference from the others. Tlie other necessary part of a radio receiver is the detector. The function of this portion of the receiver Is to utilize the small currants in the tnner that are set up by s transmitting station and make them audible through the medium of a telephone receiver. If the telephone receiver were connected directly to the tuner the current would not ojierate the dla- phntgtn of the receiver and even If the diaphragm were set in motion It would be too fast a motion to lie picked up by the human ear. In a simple receiver the detector usually consists of two pieces of mineral In contact or s piece of mineral in contact with a metallic spring. Either combination Is known as a crystal detector. A detector of this type Is nothing more than a rectifier; that la, when an alternating currant la applied at tha terminals the current Is allowed to flow only In one direction. k eM, 4.

Like light, heat and sound, radio energy is propagated in the form of a wave motion. Every one is familiar with the wave motion set up on the surface of a still hotly of water by the dropping of a stone into It. Every time a point on the surface of the waves goes through a complete set of motions and starts to repeat those motions the ware is said to have gone through a cycle. The number of complete cycles gone through per second Is the frequency. The human enr Is responsive to sound frequencies up to a few thousand cycle per second hut is not cnpuMe of reiqNiiidlng to the higher frequencies encountered In rudlo. Arbitrarily a frequency of loss thun 10.000 cycles Iiiis been culled an audible frequency one which can lie lieurd and fro qncncies above lo.um cycl,, radio or inaudible frequencies liecnuae they cannot be heard by the human car. The particular t.vie of wave which propagntes radio energy Is an electromagnetic wave. All of us hare seen hits of Iron und steel attracted by the little toy magnets made up in the form of liorseahncK. Tills attraction of the magnet for the lilt of Iron ami steel showed tlie existence of a magnetic field abnnt tlie tips of the magnet and tlda same kind of a field propagate force, except that tlie electro-magnetunlike the toy magnet, Its power conies off In the form of wavy nun ions. This c forro propagates radio energy In ull directions. The medium that tmnsmlta the electro-le waves Is the same medium that transmits light the ether. This medium Is supiaiseil to fill all spnee, even tlmt occupied by fluids and solids. Little is known alwut its properties. In radio It Is more common to speak of wave length than frequency.
