What is a longitudinal wave? Learn the definition and various parts of a longitudinal wave. Understand the amplitude and wavelength of a...
WANGLi-li , in Foundations of Stress Waves, 2007 6.2.2 Longitudinal visco-elastic waves propagating in Maxwell bars The longitudinal waves in Maxwell bars can be discussed in a similar way, for which the governing equations consist of Eqs. (2.12), (3.13), and (6.4), namely: (6.26) ...
Plane longitudinal waves propagating in a Slepyan-Palmov medium that consist of a carrier medium and an ensemble of nonlinear oscillators are considered. The system of equations of dynamics is reduced to one equation for the longitudinal displacement of the carrier medium. The propagation of harmonic...
The longitudinal bar has a lengthL, a widthaand a thicknessb(Fig. 13.12); the electric field is parallel to thelongitudinal axis. It is assumedthat simple harmoniclongitudinal wavespropagating along thex-direction have a displacement given by: ...

Zonal and meridional winds in the equatorial mesosphere and lower thermosphere (65–98 km) measured at two sites separated by 94° in longitude are used to study the zonal structure of planetary-scale waves. The data were obtained with MF radars located at Pontianak (0°N, 109°E)and Chris...
(b) Bats can ascertain distances, directions, nature and size of obstacles without any eyes, (c) a violin note and sitar note may have the same frequency, yet we can distinguish between the two notes, (d) Solids can support both longitudinal and transverse waves, but only longitudinal waves...
2 We demonstrate an all-optical strategy for realizing spherical three-dimensional (3D) super-resolution (∼ λ3/22) spot arrays of pure longitudinal magnetization by exploiting a 4π optical microscopic setup with two high numerical aperture (NA) objective lenses, which focus and interfere two ...
The only longitudinal study (Leibovitz et al., 2021) used only two waves of data and did not separate between-person from within-person effects. Yet the processes of interest are specifically concerned with what happens at the within-person level, that is, whether the ado...
