Longitudinal wave(纵波) in a spring(弹簧) actually consist of a series of (一连串的) coupled harmonic oscillations(耦合简谐振荡), a conclusion that can be extended(推广) to longitudinal waves in all media(介质).相关知识点: 试题来源:
6 Sound is a longitudinal wave.(a) Sketch a representation of a longitudinal wave. On your sketch. indicate and label a distance to show the wavelength,. mark and label the centre of one compression,. mark and label the centre of one rarefaction.[3](b) A longitudinal wave passes from ...
A longitudinal wave causes the particles of a medium to move parallel to the direction of the wave.Figure 15-2b shows a longitudinal wave .Note that the motion of the spring is parallel to the direction in which the wave is moving .Thus the difference between transverse and longitudinal ...

The wave forms for longitudinal waves reflected from a thin but uniform layer have been studied theoretically [1–5], on models [6–7], and in actual media [2, 4], Recently, theoretical studies have appeared which develop the wave forms for waves reflected from a periodic sequence of thin...
(a) Obtain the relation connecting particle velocity and wave velocity. (b) What is wavefunction? What is its significance ? (c) When a longitudinal wave passes through a medium (liquid or gas) write down the expression for the pressure amplitude of the wave. ...
