Nodes and anti-nodes are formed in stationary waves. In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node and the immediate next anti-node is one fourth of a wavelength. Therefore the wavelength of the wave = 5 cm * 4 = 20 cm....

hope it help you ..
