横波 Transverse wave(重定向自Displacement wave)
![]() ![]() ![]() ![]() 横波是介质振动方向和波行进方向垂直的一种波。若此波沿着x轴移动,则介质的振动方向为与x轴垂直的方向上。举例来说绳波就是一种横波。水波在外表看起来具有横波的样子,但实际上水分子的振动并非单纯的与波前进的方向垂直或平行,因此并不适合讨论其为横波或纵波。 地震时产生的横波的传递速率小于纵波(纵波包括声波和某些地震引起的震波(P波),其特征为介质粒子移动方向和行进方向平行)。

Transverse wave 横波(重定向自Displacement wave)
![]() ![]() ![]() ![]() A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave. With regard to transverse waves in matter, the displacement of the medium is perpendicular to the direction of propagation of the wave. A ripple in a pond and a wave on a string are easily visualized as transverse waves. |
