5. History of phone  A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The word telephone has been adapted into the vocabulary of many languages. It is derived from the Greek: τ ῆ λε, tēle, "far" and φωνή, phōnē, "voice", together meaning "distant voice".

8. Theory of phone  When we speak against the side of the cups, sound waves will shake bottom of the cup. The vibrations transmit to the bottom of another cup via a string. The bottom of the cup shakes air, producing the same sound waves. When our eardrum vibrates then we can hear each other's voice.  This proves that sound can be transmitted by vibrating air. You need to make sure the rope is tense or the sound waves won’t be transmitted.
