First phone
On November 26, 1876 Alexander Graham Bell made the first phone ever. It looked like a tube that you talked into. It was $5 and the materials are wood, iron, brass, and mica. Function is when a person speaks into a telephone, the sound waves created by his voice enter the mouthpiece. An electric current carries the sound to the telephone of the person he is talking to. A telephone has two main parts: (1) the transmitter and (2) the receiver. -
