AUGUST ADOLPH EDUARD EBERHARD KUNDT (1839-1894), German physicist, was born at Schwerin in Mecklenburg on the, 8th of November 1839.
As an original worker Kundt was especially successful in the domains of sound and light.
Kundt and E.
Kundt and Warburg applied the method to find y for mercury vapour (Pogg.
Kundt also obtained results in general agreement with the formula (Rayleigh, Sound, ii.
Kundt found that similar effects occur with a large number of substances, in particular with all those which possess the property of "surface colour," i.e., which strongly reflect light of a definite colour, as do many of the aniline dyes.
Kundt, is that exhibited by the vapour of sodium.
Kundt,' who initiated this line of investigation, came to the conclusion that the absorption spectra of certain organic substances like cyanin and fuchsin were displaced towards the red by the solvent, and that the displacement was the greater the greater the dispersive power of the solvent.
The same value had previously been found for mercury vapour by Kundt and Warburg, and had been regarded as confirmatory of the monatomic character attributed on chemical grounds to the mercury molecule.
This Appears To Be Actually The Case For Monatomic Gases Such As Mercury Vapour (Kundt And Warburg, 1876), Argon And Helium (Ramsay, 1896).
Kundt prepared metallic films of iron, nickel and cobalt, and obtained powerful negative optical rotation with them (Wied.
