Plane wave In the physics of wave propagation, a plane wave (also spelled planewave) is a constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of constant peak-to-peak amplitude normal to the phase velocity vector.It is not possible in practice to have a true plane wave; only a plane wave of infinite extent will propagate as a plane wave. =======Image-Copyright-Info======= Image is in public domain Author-Info: Onde_plane_3d.jpg: Fffred derivative work: Quibik (talk) Image Source: https://en.wikipedia.org/wiki/File:Pl... =======Image-Copyright-Info======== -Video is targeted to blind users Attribution: Article text available under CC-BY-SA image source in video    • Plane wave
