How is the sound produced?

उत्तर
Sound is produced by vibrating objects. When an object moves back and forth rapidly, it is said to be vibrating. These vibrations cause the particles of the surrounding medium (like air) to vibrate as well, and this vibration travels in the form of sound waves to our ears.
For example, when we pluck a stretched rubber band, it vibrates and produces sound. Similarly, the strings of a guitar or vocal cords in our throat produce sound through vibrations.
