| Experiments on the refrangibility of the invisible rays of the Sun. |
| It corresponds in refrangibility with the yellow band of the spectrum. |
| Rays which differ in refrangibility may be parted and sorted from one another. |
| As the angle of incidence is increased, the reflected light becomes brighter and rises in refrangibility. |
| This confirmed his previous conclusion that the rays increase in refrangibility from red to violet. |
| Here, by the interposition of the platinum foil, the refrangibility of the ultra-red rays is so exalted as to render them visible. |
