By a variety of experiments upon sunlight refracted through a prism, he concluded that rays of light which differ in color differ also in refrangibility - a discovery which suggested that the indistinctness of the image formed by the object-glass of telescopes was due to the different-colored rays of light being brought to a focus at different distances.
