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 travel from one place to another
- Both particles, as well as disturbances, travel from one place to another
Hint:
The sound travels in the air when the disturbance passes from one place to another.
The correct answer is: The disturbance travel from one place to another
- The sound is a mechanical wave that propagates in a medium.
- It travels as a disturbance that can be defined as vibration.
- The sound waves travel faster in a solid medium.
