Description
Interference pattern shown in the separation of light wavelengths through two diffraction gratings.
Figure 18 from the book The glaciers of the Alps, by John Tyndall (new edition, Longmans, Green, and Co., London, 1896).
Inscribed below: ‘INTERFERENCE SPECTRA, PRODUCED BY DIFFRACTIONS. FIG.18. to face p.235.’
The accompanying text (p.235) states: ‘By varying the shape of the aperture we alter the form of the chromatic image…If we multiply our slits or apertures the phenomena augment in complexity and splendour. To give some notion of this I have copies from the excellent work of M. Schwerd the annexed figure (Fig.18) which represents the gorgeous effect observed when a distant point of light is looked at through two gratings with slits of different widths.’
Friedrich Magnus Schwerd (1792-1871), German teacher and physicist, author of Die Beugungserscheinungen…(Mannheim, 1835).
John Tyndall (1820-1893), British physicist and mountaineer, was elected a Fellow of the Royal Society in 1852.
