Wave Properties and Behavior

The video introduces waves, focusing on their role in energy transfer. It distinguishes between electromagnetic and mechanical waves, with a deeper dive into mechanical waves, including transverse, longitudinal, and surface waves. Phet simulations are used to visualize these concepts. Key wave terms like crest, trough, wavelength, and amplitude are defined. The video also covers the mathematical relationship between wave velocity, frequency, and wavelength, emphasizing that velocity is determined by the medium, frequency by the source, and wavelength adjusts accordingly.
