Index of Refraction of Nickel
The index of refraction, μ the extinction coeff., k; and the reflecting power, R, of electrolytic nickel were measured by R. S. Minor, F. Rother and K. Lauch, K. Lauch, H. Hauschild, A. de Gramont, M. Luckiesh, R. Hamer, I. C. Gardner, A. Kundt, M. Laue and F. F. Martens, P. Bergman and W. Guertler, F. Hlucka, A. Q. Tool, H. du Bois and H. Rubens, A. Pfluger, W. Rathenau, and E. Hagen and H. Rubens. The results of W. Meier for wave-lengths λ=589 to 668, for electrolytic nickel, and of G. Pfestorf for λ=578 to 254, are:
The observations of G. Quincke for λ up to 527, 589, and 656, and of P. Drude for λ=589 and 630, and of M. Laue and F. F. Martens for λ=630:
Observations were also made by H. von Wartenberg, M. Luckiesh, G. Pfestorf, P. R. Gleason, F. Henning, L. R. Ingersoll, C. Zakrewsky, and A. Q. Tool. I. C. Gardner studied the reflecting power in the ultra-violet; E. Hagen and H. Rubens, the variation of the emissive power with temp.; and E. Hagen and H. Rubens found for the reflecting power:
J. H. Gladstone gave for the refraction equivalent 10.4, and for the sp. Refraction, 0.177. W. J. Pope gave 12.84 for the refraction equivalent of nickel. H. Knoblauch gave 77.50 for the polarization angle for the ultra-red heat rays, and 70.00 for yellow light. C. J. Davisson and L. H. Germer studied the polarization of the reflected electron waves; W. Lobach, and A. Kundt, the electromagnetic rotation of the plane of polarized light; and L. R. Ingersoll, H. E. J. G. du Bois, J. G. Leathern, K. H. von Klitzing, A. Pietzcker, C. J. Gorter, E. Hirsch, W. Lobach, P. D. Foote, and C. Snow, the Kerr effect. |
