A stone is dropped in a liquid at rest in a tank The fig a below shows circular wave fonts waves produced at the centre of a circular ripple tank Two corks A and B floats on the water moves up down on the surface as the wave passes The wavelength of the wave is 8 0cm The Fig b shows how the displacement of A varies with time ii iii iv 8 0cm cork A a b c d cork B a 1 Name the type of waves produced on watersurface Longitudinalwave a c Soundwave 2 Displacement mm What is the frequency of thewave a 4Hz b 0 4Hz 2 0 25 0 50 b d b 0 75 1 00 1 25 time s EMwave What is the amplitude of the vibrations of A as wavepasses a 2mm b 0 25mm c 0 50mm d 8mm The horizontal distance between A and B is half the wavelength of the wave Then the displacement of B with timeis same as that of A with equalmagnitude opposite to that of A with equalmagnitude double in magnitude as that ofA half in magnitude as that ofA Transversewave c 2Hz d 0 2Hz v If the distance between the centre of the ripple tank and its edge is 40 cm Then the tin taken by the wave to travel from the centre of the tank to the edgeis a 5s b 2 5s
