Which part of a sound wave has the highest density of particles?

Sound waves are considered mechanical waves primarily because

• sound waves require an electro magnetic field to travel through

• sound waves require a physical medium to travel through

• they require movement of a mechanical object

• sound waves must move components of your ear physically
