横波与纵波 / Transverse & Longitudinal
横波
(Transverse Wave)
粒子振动方向与波形或能量传播方向垂直 / The direction
of particle vibration is perpendicular to the direction of wave propagation or energy
transmission.
纵波
(Longitudinal Wave)
粒子振动方向与波形或能量传播方向平行 / The direction
of particle vibration is parallel to the direction of wave propagation or energy transmission.
横波 Transverse Wave
纵波 Longitudinal Wave
演示要点 /
Key points
同步质点 (Particle P & Q)
两者相距一个波长，振动步调完全一致 / Separated by one wavelength,
their vibrations are perfectly synchronized.
局部振动 (Local Vibration)
粒子仅在平衡位置附近振动，不随波迁移 / Particles vibrate locally and
do not travel with the wave.
