This letter was shown by Arago to Fresnel, who at once saw that it presented the true explanation of the non-interference of beams polarised in perpendicular planes, and that the latter effect could even be made the basis of a proof of the correctness of Young's hypothesis" for if the vibration of each beam be supposed resolved into three components, one along the ray and the other two at right angles to it, it is obvious from the Arago-Fresnel experiment that the components in the direction of the ray must vanish" in other words THAT THE VIBRATIONS WHICH CONSTITUTE LIGHT ARE EXECUTED IN THE WAVE-FRONT.""

First appearance of this importent paper in which Arago gives an account of his discovery of how iron and steel could be magnetized by the action of the voltaic current, THE FIRST STEP TOWARDS THE ELECTRIC TELEGRAPH. ""Arago .... made several important contributions to electromagnetism on his own. On 20 September 1820 he announced the discovery of the temporary magnetization of soft iron by an electric current, which suggested to Ampère a theory about the nature of magnetic ""currents"" and provided the technological key to the electric telegraph. Ampère calculated that the magnetic power could be multiplied by twisting the current-carrying wire into a helix, and with Arago he carried out the first experiments on primitive solenoids. In his historical articles Arago was always careful to credit Ampère with the major share of this discovery, which ultimately depended upon Ampère’s mathematical theory.""(DSB).Arago formed a close freinship with Fresnel,whose views on the nature of light he ardently supported. He assisted Fresnel in some of his most importent work and made original discoveries in the same field.Magie ""A Source Book in Physics"", p. 443 ff.

First appearance of the joint report. This investigation of Fresnel's paper by Arago (mainly written by Arago as a polemic directed at Biot) and Ampère is a central document in the rather bitter confrontation between Arago and Biot on the wave theory of light put forward by Fresnel.Fresnel's paper is the first part of three of his ""Calcul des teintes"".
