"Mr. Watson, come here. I want to see you."
How It Works
Bell achieved this accomplishment by having a needle glued to a cork, which was pointing at a glass of sulphuric acid. His voice caused the needle to vibrate. This needle was wired to a battery. The strength of the vibration converted the sound waves into an electric signal. A wire moved the signal to a reciever. The first words, "Mr. Watson, come here. I want to see you," were spoken when Bell spilled some of the acid on his pants. Mr. Watson rushed in when we had heard it. The first telephone call had been made!
Evolution Of Phones
Impact On Society
Before the telephone, people only sent important messages because they had to be delivered either by mail or messenger. The telephone allowed people to send messages easily and efficiently. Bell's invention evolved into the cell phones we all rely on today.
