The Green Flash at Sunset

Abstract

OBSERVATIONS of the green flash have frequently been recorded in NATURE, and Lord Rayleigh1, by simple and beautiful experiments with an artificial source of light and a prism the dispersion of which was equal to atmospheric dispersion, has imitated the chief phenomena of the coloured flash observed at sunset. This experimental imitation strongly supported the generally accepted view that the green flash is primarily due to atmospheric refraction, dispersion and differential scattering. The discussion following Lord Rayleigh's paper read before the Physical Society indicated, however, that before a satisfactory explanation of all the observed phenomena could be given, further observations were required.
