The vibrating object produces a series of compressions and rarefactions, one after the other in the medium. These pulses travel one behind the other as the sound waves move forward. When this sound wave reaches our ear, it forces the tympanic membrane to vibrate and thus causes the sensation of hearing.

Explanation:
Rarefaction:
- When a vibrating object moves backwards, it creates a region of low pressure in the medium called rarefaction.
- This means that the particles in the medium are spread further apart, creating a decrease in pressure in that region.
- Rarefaction is the opposite of compression, where the particles are closer together and the pressure is higher.
Significance of Rarefaction:
- Rarefaction plays a crucial role in the propagation of sound waves through a medium.
- It allows for the transmission of waves by creating areas of lower pressure that enable the wave to travel through the medium.
- Without rarefaction, sound waves would not be able to propagate effectively through a medium.
Relationship to Vibrating Object:
- The rarefaction created by a vibrating object moving backwards is a result of the oscillatory motion of the object.
- As the object moves back, it pushes the particles in the medium apart, leading to the formation of a rarefaction region.
- This phenomenon is essential for the transmission of sound waves and is a fundamental concept in the study of wave mechanics.
In conclusion, rarefaction is a critical concept in the study of wave propagation, particularly in the context of sound waves. When a vibrating object moves backwards, it creates a region of low pressure in the medium known as rarefaction, which enables the transmission of waves through the medium. Understanding rarefaction is essential for comprehending the behavior of waves and their interactions with different mediums.
