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:
Energy is transmitted by waves from one place to another.
The correct answer is: The disturbance travel from one place to another
- Waves transmits energy not matter/particles.
- The sound waves can travel in the air when the disturbance travel from one place to another.
- So, the correct option is c.
