Appendix D: The Wave Vector. In this appendix we briefly address the concept of the wave vector and its relationship to traveling waves in 2- and 3-dimensional space, but first let us start with a review of 1-dimensional traveling waves.
24 Απρ 2022 · The large arrow is a vector called the wave vector, which defines (1) the direction of wave propagation by its orientation perpendicular to the wave fronts, and (2) the wavenumber by its length. We can think of a wave front as a line along the crest of the wave.
15-2 Types of Waves: Transverse and Longitudinal. Figure 15-9: A water wave is an example of a surface wave, which is a combination of transverse and longitudinal wave motions.
For an arbitrarily-shaped, left-moving transverse traveling wave, described by the function y(x, t) = f(x + vxt), the x-position of a given point on the waveform decreases as time increases. This wave propagates with longitudinal wave velocity vx m/sec in the x-direction.
6.1.3 Transverse and longitudinal waves All types of wave can be divided into two groups – transverse and longitudinal. Look at the animations on the website linked below: https://www.acs.psu.edu/drussell/demos/waves/wavemotion.html Carefully observe how the particles in transverse and longitudinal waves move.

Transverse waves are the waves that have the classical wave shape everyone thinks of when they imagine a wave. Illustration 1: Transverse wave. Particles of the medium move perpendicular to the direction the transverse wave itself is moving.
