Question
In vacuum but not in a medium
- The medium particles travel from one place to another
- There is no humudity in the air
- The disturbance travel from one place to another
- Both particles, as well as disturbances, travel from one place to another
Hint:
Disturbance travels from one place to another to show wave propagation
The correct answer is: The disturbance travel from one place to another
Waves mostly require medium because they rely on particles for motion
