A sinusoidal plane wave is a specific type of wave that propagates through a medium with a sinusoidal form. It is characterized by its smooth and regular oscillations, with the following key features: 1. **Sinusoidal Shape**: The wave's displacement as a function of position and time is described by a sine or cosine function.
