Leonhard Euler, Conjectura Physica circa Propagationem soni ac luminis [Tomus II], published Berlin: Ambrosius Haude and Johann Carl Spener, 1750, with one folding engraved plate.
Translated to Physical conjectures on the propogation of sound and light with other dissertations: on amicable numbers, on natural equations, and on the rectification of ellipses, usually referred to as Opuscula Varii Argumenti, Volume 2, this work is part of a three-volume series. In ‘Conjectura physica circa propagationem soni ac luminis’ (II, pp. 1-22), Euler further investigates the propagation of light in the aether, comparing it to that of sound in air.
