Defocusing waves

Defocusing waves occur when energy in a wave spreads out or disperses, reducing the wave's intensity and concentrating less energy in a specific area. In physical systems, this can happen when waves pass through varying media or encounter obstacles that cause their paths to diverge. For example, in optics, a lens causes light waves to spread out, leading to a blurry image, a process called defocusing. Similarly, in ocean waves, changes in water depth can cause wave energy to disperse, reducing their impact. Overall, defocusing describes the process where wave energy becomes more spread out, decreasing the wave’s localized strength.
