Question
The sound can travel in the air when:
- The medium particles travel from one place to another.
- There is no humidity in the air.
- The disturbance travels from one place to another
- Both particles as well as disturbances, travel from one place to another.
Hint:
The disturbance travels from one place to another
The correct answer is: The disturbance travels from one place to another
sound waves travel through air when disturbance travel through one place to another.
