Question

In vacuum but not in a medium

  1. The medium particles travel from one place to another
  2. There is no humudity in the air
  3. The disturbance travel from one place to another
  4. Both particles, as well as disturbances, travel from one place to another

hintHint:

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
