The correct answer is option 'C' - disturbance.
Explanation:
A disturbance is the cause of sound production in a medium. When an object vibrates or moves, it creates a disturbance in the surrounding medium. This disturbance then travels through the medium in the form of waves, which we perceive as sound.
Sound waves are mechanical waves that require a medium to travel through, such as air, water, or solids. When an object vibrates, it sets molecules in the medium in motion. These molecules then collide with neighboring molecules, transferring the energy and causing them to vibrate as well. This creates a chain reaction, resulting in the propagation of sound waves through the medium.
The sound waves consist of compressions and rarefactions. In a compression, the molecules are closely packed together, while in a rarefaction, the molecules are spread apart. As the disturbance travels through the medium, the molecules oscillate back and forth, creating a pattern of compressions and rarefactions.
These compressions and rarefactions of molecules are responsible for the transfer of energy in the form of sound. When the sound waves reach our ears, they cause the eardrums to vibrate, which is then interpreted by our brain as sound.
In summary, the sound is produced due to the disturbance created by the vibrating object in the medium. This disturbance sets the molecules in the medium in motion, creating compressions and rarefactions that propagate as sound waves.
