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:
aDiffraction of light on a longitudinal acoustic wave in a glass material is provided by the P11 photoelastic constant, if light is polarized along the sound propagation direction, or P12 constant for an orthogonally polarized beam. The figure of merit M2 of the material is different for the tw...
英语翻译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 t

Longitudinal waves in a dusty plasma are studied using fluid models where we regard the dust as being immobile. The variation of the charge on the dust particles due to the wave field is taken into account. Three wave modes are considered; the ionacoustic wave, the electrostatic ion cyclotron...
A three-dimensional focus shaping technique using the combination of cylindrical polarization with binary diffractive optical element is proposed. The ener... W Chen,Q Zhan - 《Optics Communications》 被引量: 119发表: 2006年 Specific Directions of Longitudinal Wave Propagation in Anisotropic Media Plan...
A technique is presented for accurate measurement of the longitudinal wave velocity up to 1050 掳C in sintering powder compacts. The technique uses laser g... LP Martin,M Rosen - 《Ultrasonics》 被引量: 26发表: 1997年 Elastic Properties of Mullite Single Crystals up to 1400°C Elastic consta...
A longitudinal wave is a type of mechanical wave that travels through a medium by causing the particles of the medium to vibrate parallel to the direction of the wave's motion. This means that the particles of the medium are moving back and forth in the same direction that the wave...
A homogeneous isotropic compressible Hadamard material has the property that an infinitesimal longitudinal homogeneous plane wave may propagate in every direction when the material is maintained in a state of arbitrary finite static homogeneous deformation. Here, as regards the wave, 'homogeneous' means ...
Based on the established rigorous theory for two-dimensionally periodic (2DP) medium, Longitudinal propagation in Dielectric Waveguide Array (DWA) was analyzed in detail. Firstly, given longitudinal wave vector ( k z ), Brillouin dispersion relations between transversal wave vectors were analyzed. Inter...
