Limiting factor in determining if wave will pass through?

  1. Jun 16, 2013 #1
    Hi, can anyone explain to me why wavelength is a limiting factor in determining whether a radio wave will pass through an object, a wall for example?

    Thank!

    You want to think in terms of resonance ... what is the mechanism that stops an EM wave from passing through an object? After that you have to think of the role interference and diffraction would play.
