actually the standing wave is also having the same frequency as the incident and reflected waves how ever the amplitude is the addition of amplitudes of forward and reverse moving waves.
the anti node (positive) is turn to anti node(negative) and repeating this appears of standing wave. the node of forwading wave and the node of backward wave meets at one point during their travel the node of forward wave meet the next node of backward wave.
time taken to meet the node of forward wave with the next node of back ward wave is called frequency similar in the case of antinodes also.
