c/n or n·c?

THESIS Main (won, 19th century): the wave theory of light (Young's 1801 two-slit fringes; Fresnel). Ghost (lost): Newton's corpuscles, which explain refraction by light speeding up in water (v = n·c) where waves slow down (v = c/n). Foucault (1850) measured light slower in water, and the wave won (LIT). Then photons (Einstein 1905) revived the particle, so both survive in quantum mechanics. Cross-link Experimentum Crucis and Newton recombines.

COMPUTEDThe two-slit intensity pattern (main) against the corpuscle prediction of two bright bands (ghost). The two models' speeds in water differ by a factor n² = 1.78.

MNEMONIC "In water, waves wade; corpuscles would race."
