{{#category_index:P|principle of reciprocity}} The seismic concept that the same trace would result if source elements were replaced with receiver elements and vice-versa. Similar concepts are involved with other methods, for example, interchanging current and potential electrodes in electrical exploration. A consequence of linearity. Reciprocity is not valid with converted waves unless the directional senses of the source and receiver are also interchanged.
