This 15-minute video is the first in a 6-part series of educational videos on properties and behavior of waves. As the title implies, the video goes beyond 2D Slinky models to introduce beginners to the basics of 3-dimensional waves. Through narrated demonstrations and animations, the video takes a deep look at the properties of longitudinal and transverse waves: amplitude, frequency, wavelength, period, and wave speed. It then introduces viewers to the three dimensions found in water waves, with a first-rate depiction of the "z" axis. Professional scripting, production, and editing serve to provide a much deeper learner experience than traditional lecture demonstrations.
