interference phenomena

Interference is a phenomenon that occurs when two or more waves overlap, combining their energies. Depending on how their peaks and troughs align, they can either reinforce each other (constructive interference), creating a louder or brighter effect, or cancel each other out (destructive interference), resulting in reduced or no signal. This process is common with light, sound, and water waves, and explains patterns like the bright and dark bands in a ripple tank or the varying brightness of overlapping light beams. Interference illustrates how waves interact, influencing the behavior of many systems in nature and technology.
