How sound is produced ?

Explanation

### Step-by-Step Solution:

1. **Understanding Sound Waves**: Sound is a type of mechanical wave, which means it requires a medium (such as air, water, or solids) to travel through. Unlike electromagnetic waves, sound cannot travel through a vacuum.

2. **Vibrations as the Source of Sound**: Sound is produced by vibrations. When an object vibrates, it causes the particles of the medium around it to also vibrate. This disturbance in the medium creates sound waves.

3. **Example of Sound Production**: A common example of sound production is a musical instrument, such as a guitar. When the strings of a guitar are plucked, they vibrate. These vibrations disturb the surrounding air particles, creating sound waves that travel through the air.
