How did Bell's telephone work?
knowing that sound gives off waves, like ripples in water, they travel into the mouth piece there the sound waves are copied by the trasmitter behind the transmitter are carbon grains that when an electric current is traveling makes the grians vibrate and that alters the resistance of the grains as a whole. In this way the sound makes more and less current flow in the circuit in proportion to the sound.
At the other end was a coil of wire within a magnet attached to a diaphragm. The variations in current caused the wie tomove in the magnetic field and so make the diaphragm vibrate in sympathy. Vibrations (as we learnt at the beginning) move air and this makes sound!

It looked uncannily similar to Elisha Gray's patent application, lodged just before his own.
It had separate microphone and earpiece, on cotton covered plaided wires.

It was in the summer when he met Watson. Over the summer they thought of the idea. But the first idea was to send 2 messages on the telegram at a time. Pretty soon, the idea faded away because somebody else was already working on sending 4 messages at a time. So, then they got the idea of a invention that would send your voice across a wire. It seemed impossible but it worked!
How has Alexander graham bell's invention changed our lives?
Alexander Graham Bell
Physicist, born in Edinburgh, Scotland, 3 March 1847. He is a son of Alexander Melville Bell, mentioned below, and was educated at the Edinburgh high school and Edinburgh University, receiving special training in his father's system for removing impediments in speech. He removed to London in 1867, and entered the University there, but left on account of his health, and went to Canada with his father in 1870. In 1872 he took up his residence in the United States, introducing with success his father's system of deaf-mute instruction, and became professor of vocal physiology in Boston University. He had been interested for many years in the transmission of sound by electricity, and had devised many forms of apparatus for the purpose, but the first public exhibition of his invention was at Philadelphia in 1876. Its complete success has made him wealthy. His invention of the "photophone," in which a vibratory beam of light is substituted for a wire in conveying speech, has also attracted much attention, but has never been practically used. It was first described by him before the American association for the advancement of science in Boston, 27 August 1880.
After the shooting of President Garfield, Professor Bell, together with Sumner Tainter, experimented with an improved form of Hughes's induction balance, and endeavored to find the exact location of the ball, but failed. Professor Bell has put forth the theory that the present system of educating deaf-mutes is wrong, as it tends to restrict them to one another's society, so that marriages between the deaf are common, and therefore the number of deaf-mute children born is on the increase. His latest experiments relate to the recording of speech by means of photographing the vibrations of a jet of water. He is a member of various learned societies, and has published many scientific papers. He has lived for some time in Washington, District of Columbia.
