Professor Vedral,

A delightful metaphor, but there’s a critical flaw:

The analogy between light and sound rainbows collapses under dispersion relations. In acoustics, the medium defines a strictly linear dispersion , while for light in dispersive media (e.g., water droplets), the group velocity dispersion is what fans the spectrum.

An “acoustic rainbow” would require either nonlinear acoustic metamaterials or phonon bandgaps, not mere wave coherence. The wave equation unifies form, not spectral structure—your equivalence assumes too much from alone.

Elegant speculation, but physically orthogonal.
