Physics: Tuning Fork Vibration

During the vibration of the tuning fork, when the prongs go away from each other, what happens to the air pressure outside the prongs?

What term is used to describe the region with high pressure and high density when the prongs of the tuning fork are close to each other?

When the prongs of the tuning fork come close to each other during vibration, what happens to the air molecules near them?

What term is used to describe the region where air is at low pressure and low density when the prongs of the tuning fork are close together?

What happens to the air molecules in the region where rarefaction occurs?

How do compression and rarefaction created by the tuning fork prongs lead to hearing a sound by vibrating the ear-drum?

What is the term used to describe the region where air is at high pressure and high density when the prongs of the tuning fork go away from each other?

When the tuning fork prongs come close to each other during vibration, what term describes the region with low pressure and low density?

What happens to the air pressure in the region when compression is created by the tuning fork prongs moving away from each other?

How is rarefaction defined in the context of the tuning fork vibrations?

What happens to the air molecules near the tuning fork prongs when they go away from each other?

During the vibration of a tuning fork, what is the term for the motion where the air molecules near the prongs get more space to move away from each other?
