Telephone noun [ Greek ... far off + ... sound.] (Physics) An instrument for reproducing sounds, especially articulate speech, at a distance. » The ordinary telephone consists essentially of a device by which currents of electricity, produced by sounds through the agency of certain mechanical devices and exactly corresponding in duration and intensity to the vibrations of the air which attend them, are transmitted to a distant station, and there, acting on suitable mechanism, reproduce similar sounds by repeating the vibrations. The necessary variations in the electrical currents are usually produced by means of a microphone attached to a thin diaphragm upon which the voice acts, and are intensified by means of an induction coil. In the magnetic telephone , or magneto- telephone , the diaphragm is of soft iron placed close to the pole of a magnet upon which is wound a coil of fine wire, and its vibrations produce corresponding vibrable currents in the wire by induction. The mechanical , or string , telephone is a device in which the voice or sound causes vibrations in a thin diaphragm, which are directly transmitted along a wire or string connecting it to a similar diaphragm at the remote station, thus reproducing the sound. It does not employ electricity.
Telephone transitive verb To convey or announce by telephone.
Telephone exchange A central office in which the wires of telephones may be connected to permit conversation.

» A telescope assists the eye chiefly in two ways; first, by enlarging the visual angle under which a distant object is seen, and thus magnifying that object; and, secondly, by collecting, and conveying to the eye, a larger beam of light than would enter the naked organ, thus rendering objects distinct and visible which would otherwise be indistinct and or invisible. Its essential parts are the object glass
, or concave mirror
, which collects the beam of light, and forms an image of the object, and the eyeglass
, which is a microscope, by which the image is magnified. Achromatic telescope
. See under Achromatic .
-- Aplanatic telescope
, a telescope having an aplanatic eyepiece.
-- Astronomical telescope
, a telescope which has a simple eyepiece so constructed or used as not to reverse the image formed by the object glass, and consequently exhibits objects inverted, which is not a hindrance in astronomical observations.
-- Cassegrainian telescope

, a form of reflecting telescope. See under Gregorian .
-- Herschelian telescope

-- Newtonian telescope
, a form of reflecting telescope. See under Newtonian .
-- Photographic telescope
, a telescope specially constructed to make photographs of the heavenly bodies.
-- Prism telescope
. See Teinoscope .
-- Reflecting telescope
, a telescope in which the image is formed by a speculum or mirror (or usually by two speculums, a large one at the lower end of the telescope, and the smaller one near the open end) instead of an object glass. See Gregorian, Cassegrainian, Herschelian, & Newtonian, telescopes , above.
