A plane wave is a type of wave that has a constant phase front and travels in a uniform direction. In simpler terms, it can be thought of as a wave where the wavefronts (surfaces of constant phase) are infinite parallel planes. Plane waves are often used as an idealization in physics to simplify the analysis of wave phenomena, such as light waves, sound waves, and other types of electromagnetic or mechanical waves.
