【Abstract】 The design of the hardware circuit and the software program for the wave propagation demonstration instrument controlled by programming oneboard computer is presented.The instrument can be used to demonstrate the wave movement toward left and right,the static wave pattern,the spots along and opposite the move direction in the propagation of wave,the vibration of the unitary material point,etc.The velocity of the wave movement is adjustable and the movement can be shown step by step.更多还原
