Question
In which of the following media can non-mechanical waves travel?
- In a medium, but not in a vacuum
- Neither in a medium nor a vacuum
- In a vacuum as well as in a medium
- In a vacuum, but not in a medium
Hint:
The non-mechanical waves travel through the vacuum as well in the medium.
The correct answer is: In a vacuum as well as in a medium
- The mechanical waves cannot propagate in a vacuum.
- The transverse waves are not propagated in gases as well as liquids.
- The non-mechanical waves travel through the vacuum and other mediums.
