Question

16: The colored dots in Georges Seurat's paintings are about 0.002 m in diameter and they basically touch each other (so Ду = 0.002 m). At large distances, the dots appear to vanish and the colors blend together due to diffraction through the pupil of your eye (apupil -0.005 m). If you stand close to one of his paintings and slowly walk backwards, eventually the dots of a certain color (wavelength) will blend together. Which color does this occur for at the shortest distance and why? b: What minimum viewing distance (L) is required for the dots of all visible colors (wave- lengths) to blend together?
