Source disturbs the medium by vibration:

- The type of vibration is known as ‘Oscillation’

- AKA (Also Known As) ‘Circular of continuous motion’ since wave is used to represent circulations

Medium disturbance

 

▲ Static status (Static: No motion)

Air always has an ‘ambient’ (static, encompassing atmosphere) density

 

When struck:

a. The string begins to oscillate

b. Energy is introduced to the string

▲ Compression: Increase in density / pressure

The distance the string move is determined by how much energy is transformed into the string 

 

▲ Returns to static:                                        

- The molecules follow

- The density decrease back to ambient / static

▲ The molecules spread out into the clean space

The string moves thru static to a maximum in the opposite direction: 

- These decrease the density on the Right Hand side of the string

—> This is know as ‘Rarefaction’ (the act of making less concentrated)

 

▲ The string returns to static and the whole cycle begins again without interruption
