St. Andrew’s Junior College H2 Physics 10-3 22 Ans: C Travelling wave Stationary wave A no medium required no medium required B separation between 2 adjacent points of corresponding phase is one wavelength separation between a node and the adjacent antinode is a quarter of a wavelength C amplitude of vibration is the same at all points amplitude of vibration varies with position D energy at any point is all kinetic, all potential or a mixture depending on the point and the time considered energy at any point changes from kinetic to potential and back again except at the nodes E energy is transported at a speed given by frequency multipled by the wavelength no net transport of energy 23 Ans: D Only points in the same loop or alternate loops are in phase. Points in adjacent loops are in antiphase.
