As The sunshine (still separated into its variety of colors) exits the water droplet, it accelerates because it travels back again out to the fewer dense air and is refracted (a next time) downward to at least one's eyes.

René Descartes's sketch of how Major and secondary rainbows are shaped, Discours de la Méthode, 1637.

He usually takes into consideration two theories: one particular, the rainbow is produced by the Solar reflecting in each water drop, one other, that it's produced by the Sun mirrored in a very cloud formed just like a concave mirror; he favours the latter. He also discusses other phenomena associated with rainbows: the mysterious "virgae" (rods), halos and parhelia.[73]
