Questions.1.How does the telephone work2.Which works better: taut orloose? Why?3.What happens when thevibrations (sound waves) reachthe other end of the cup?
Answer (1)
1. A traditional telephone works by converting sound waves from a person's voice into electrical signals that can be transmitted over a network of cables, wires, and switches. On the receiving end, the electrical signals are converted back into sound waves that can be heard by the person on the other end of the call.To make it more detailed, when a person speaks into a telephone microphone, their voice creates small sound waves that push against the microphone membrane and cause it to vibrate. These vibrations are then converted into electrical signals by the microphone, which are send down a line of cables to a phone exchange station.2. Whether a rope or a cable is best depends on the context and intended use.A taut rope or cable is one that is stretched tight, usually under tension. This can provide stability and support and can be useful in applications such as lifting, anchoring, or securing objects. Taut ropes/cables can also transmit force or tension, for example, in a pulley system.A loose rope or cable is one that is not taut, allowing for slack or movement. This can be useful when the cable/rope is being used to carry a load or for other purposes when flexibility or mobility is required.3. When the vibrations from a person's voice reach the other end of the telephone cup, they are detected by a small device called a diaphragm. The diaphragm converts the vibrational energy from the sound waves back into an electrical signal, which can then be transmitted over the telephone line to the receiver.
