Why is it that the amplitude of an harmonic spherical wave decreases with increasing r, while this is not the case for an harmonic plane wave?

SUMMARY
The amplitude of harmonic spherical waves decreases with increasing radius (r) due to the dispersion of energy across a three-dimensional space, while harmonic plane waves maintain constant amplitude as they propagate in a single direction. This fundamental difference arises from the geometric nature of wave propagation: spherical waves radiate energy uniformly in all directions, whereas plane waves concentrate energy along a linear path. Understanding these distinctions is crucial for applications in acoustics and wave theory.
