was on the telegraphic receiver in one room, whereas his assistant was in another room. Watson created some vibrations on an iron strip.

Do you know how the telephone works? The telephone consists of two main parts the mouthpiece and the earpiece. The mouthpiece of the telephone works as a transmitter whereas the earpiece works as a receiver. Both are enclosed in one cage and are connected by a line wire. When we speak into the mouthpiece, a diaphragm attached to it starts vibrating. In accordance with produced. The telephone line wire to the receiver of another telephone carries their current. This varying current produces vibrations in the diaphragm attached tot eh receiver, which is then converted into replicas of the original sound waves. As a result the person at the other end is able to receive the voice of the speaker. The same process is repeated between our receiver and the mouthpiece of the telephone t the other end. In this way, two people can talk with each other on the telephone.
Today, each country has a vast network of telephone lines and telecommunication satellites. You can now talk to a person on the other side of the globe because of this invention by Alexander Graham Bell.
