The de Broglie relation A - h/p can be rewritten in terms of the wave number kas p= kh. Recall that wave number is defined by k = 2 /X. Using the fact that X.= v/f. find the wave numbers kj and ka corresponding to frequencies fi and f2. In an atom an electron is confined to a space roughly 10^-10 meters if we take this to be the uncertainty in the electrons position what is the minimum uncertainty delta p in this momentum
