Question

In which of the following media can non-mechanical waves travel?

  1. In a medium but not in a vacuum
  2. Neither in a medium nor a vacuum
  3. In a vacuum as well as in a medium
  4. In vacuum but not in a medium

hintHint:

Non mechanical waves are not dependent on motion of the particles

The correct answer is: In a vacuum as well as in a medium


    Since they aren't dependent on particles they can travel in both vacuum and medium
