驻波是两列传播方向相反等幅的波叠加而成的，其特征一是____ . Standing wave is superposed by two columns of waves of equal amplitude in opposite directions of propagation. Its characteristic is:_____.
A．相邻两个波节之间的所有质元振动具有相同的振幅； The vibration of all elements between two adjacent nodes has the same amplitude;
B．相邻两个波节之间的所有质元振动具有相同的相位； The vibration of all elements between two adjacent nodes has the same phase;
C．相邻两个波节之间的所有质元振动具有相反的相位； The vibration of all elements between two adjacent nodes has opposite phase;
D．相邻两个波节之间的所有质元振动具有不同的频率； The vibration of all elements between two adjacent nodes has different frequencies;
