Which statement is wrong? A.When the wave speed increases the wavelength also increases. B.The speed of water waves is greater in a deeper region than in a shallow region. C. Troughs of the waves behave like converging lens and we see at the bottom of the tank lightened area. On the contrary, crests make us see darken area at the bottom of the water tank. D.When straight waves are reflected by curved obstacles, travel in either convergent or divergent directions, depending on the curvature of the obstacle.
