Do you really want to know it ?.... well it's pretty simple like how we travel; sound travel almost same way ...
As we walk from one place to another and that is our pattern to move .. as the same way sound has it's own patterns for movement. Like some move
This way ...
It varies which medium sound are travelling though.. it can travel on air . On metal or on water or on mud ... there must be have some medium .. without medium it cannot travell. Sound choose different patterns on different mediums .
Thank you
With love
