横向与纵向波
横向波和纵向波是波传播的两种主要类型。这两个概念非常重要,在解释与波浪力学有关的许多现象方面特别有用。在本文中,我们将将横向波与纵向波进行比较,并讨论其定义,相似性以及最终的差异。
什么是横波?
在波浪和振动中,横向波的概念是角石。横波是波的两种基本形式之一。要了解横向波,需要对波力力学的基本理解。波是一种传递能量的方法。随着波的传播,它所携带的能量也会传播。这种能量会导致途中的颗粒振荡。换句话说,通过颗粒的振荡来传播能量。在横向波中,颗粒垂直于波运动的方向振荡。必须注意的是,颗粒甚至略微略微朝着传播方向移动。对于正弦波,颗粒以简单的谐波运动振荡。 For any wave, the largest displacement of the particle from the equilibrium point is equal to the amplitude of the wave, and it is proportional to the energy carried by the wave. Waves such as light waves and other electromagnetic waves are transverse. Normal light waves have oscillations in every direction perpendicular to the propagation. A plane-polarized ray would have oscillations in only one direction.
什么是纵向波?
纵波是另一个主要类型的波,which are present in nature. The same principles of wave dynamics apply to longitudinal waves. In a longitudinal wave, the oscillations of particles are parallel to the direction of propagation. This does not mean the particles are moving with the wave. The particles only oscillate about a fixed equilibrium point in space. Since the oscillations are parallel to the movement, a pressure difference is caused. A longitudinal wave also can be considered as a pressure wave since the energy is transferred through pressure. It must be noted that unlike the transverse waves, the longitudinal waves only have one direction of oscillation. The maximum displacement from the equilibrium point is equal to the amplitude of the wave, and it is proportional to the energy of the wave. Sound waves are the best example of longitudinal waves. The pressure difference between the inside of our ear and outside varies due to pressure variation created by the sound wave. This causes the diaphragm of the ear to oscillate which is then detected by the sound sensing neurons.
纵向波和横波有什么区别? •横向波创造的振荡与传播的方向是正常的,但是纵向波会产生与波的传播平行的振荡。 •横向波在许多不同的方向上具有振荡,但纵向波只有一个方向的振荡。 •天然海浪是通过纵向和横向波的叠加产生的。 |
