    Where does natural frequency comes from?

    Is there any book I could refeer to so as to learn more on the subject?

    Where does natural frequency comes from?

    I know everything has a natural frequency that is a intrinsic property to the body in question. For example, a string vibrating has the largest amplitudes when it's vibrating near it's natural frequency, and the same thing happens with other things too (like the Tacoma Bridge). Natural...

    Does the eletromagnetic field exists everywhere?

    Could we make the same analogy for gravity? Does the gravitational field is also a unique entity, not necessarily associated with a body (a planet, a star...)?

    Does the eletromagnetic field exists everywhere?

    So, a EM field is something that exists apart from the charges? What's the role of charges and moving charges in a EM field, then? I mean: if a EM field can exist without those... Does that imply that a EM field is just one big entity, and not a collection of all the the electromagnetic fields...

    Does the eletromagnetic field exists everywhere?

    Okay, so we learn in basic physics that electric fields are created by charges and that magnetic fields are created by moving charges. After that, we learn that those two are just two faces of the same coin: the electromagnetic field. Also, we know that electromagnetic waves travel trough the...
