    Welcome to PF,

    What do you think must be present?

    Hmm, not really what I had in mind. Can you give some examples of a mechanical wave?

    P.S. You could have your answer in under five seconds from Google.

    Correct! Can you now give me examples of non-mechanical waves?

    I also read about a medium.

    That's the answer :smile: Mechanical waves require a medium through which to be transmitted, whereas non-mechanical waves require no medium.
