Wave equations

Wave equations are mathematical formulas that describe how waves, such as sound, light, or water ripples, move through space and time. They capture how the wave's shape and strength change as it travels, spreads out, or interacts with objects. Essentially, wave equations predict the behavior of waves by linking their position, speed, and time, providing a framework to understand phenomena like echoes, radio signals, or ocean waves. These equations are fundamental in physics and engineering for analyzing and designing systems involving wave propagation.
