Weigh diffraction again, when showing all sorts of wave such as sound wave, light-wave are travelling, if be held back by the object that a size is bordering on or is less than wavelengh,bypass this object, proceed, if pass the aperture that a size is bordering on or is less than wavelengh, it is a center with aperture, form the phenomenon that annular wave transmits ahead. ...
