A rainbow is formed when sunlight is refracted by spherical water droplets inside the ambiance; two refractions and a person reflection, coupled with the chromatic dispersion of water, develop the key arcs of colour.

He did, nevertheless, demonstrate the phenomenon on the diffraction of light (which had been observed by Francesco Grimaldi) by enabling that a light particle could make a localised wave in the aether.
