The longitudinal pulse and the transverse pulse. The characteristics of a wave. The transport of energy in a mechanical wave. Determining the average speed of propagation of a pulse in a long helical spring. The phenomenon of reflection and interference in a transverse wave in a spring, standing wave. The phenomenon of reflection in a longitudinal pulse. The reflection and interference of incident and reflected transverse waves. The standing wave resulting from the interference between the incident and reflected wave. The apexes and nodes of the standing wave. The vibrational speed and the propagation speed. Some formations and propagation of two-dimensional waves on a liquid surface. Pulse in a liquid medium, direction and sense of propagation. Waves generated by a point source. Waves generated by a plane source, perpendicular to the liquid surface. Determination of the speed of propagation of two-dimensional waves on a liquid surface. Determining the magnification factor. Calculating the wavelength and propagation speed, knowing the magnification factor. The reflection of a two-dimensional wave on a liquid surface. What happens to plane waves when they encounter straight barriers. What happens to plane waves when they encounter curved barriers. Identifying the focus of the reflected image in a concave barrier. The refraction of two-dimensional waves on a liquid surface. Observing refraction in regions with different depths. The waves obey the same laws of refraction studied in optics.
