For a stationary wave, which of the following statement is not true? At the nodes, the particles are at rest (zero amplitude). Distance between two successive nodes or antinodes is equal to half a wavelength. At the anti-nodes, the vibrations are of greatest amplitude. Between two successive nodes, the particles are vibrating out of phase. A water wave with a 0.50 cm wavelength in shallow water enters deep water. The angle between the incident wave front in the shallow water and the boundary between the shallow and deep regions is 32 ∘
