    Effect of Snow on the Polarization of the Sky (1887)

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE polarization of the sky has been shown experimentally by Tyndall and theoretically by Lord Rayleigh to be due to fine particles suspended in the atmosphere. According to both, the sunlight scattered at right angles to its original direction by very small particles is completely polarized in ...

    Notes: [Auszug] THE complete theory of the rainbow, as developed by Sir George Airy (Camb. Phil. Trans., vi. p. 379, 1836), besides explaining the supernumerary bows, shows that the main bow has a radius somewhat smaller than that calculated on the ordinary geometrical theory. The smaller the drops the greater ...

    Notes: [Auszug] THIS morning a very distinct halo accompanied by mock suns on either side was seen here. As the latter, owing to the altitude of the sun, were at a considerable distance outside the halo, I think the following details are worth putting on record. At 11h. 12m., Berne time, the sun's altitude ...

    Notes: [Auszug] THIS phenomenon is very common here in the winter, occurring, with few exceptions, whenever there are scattered clouds near the sun. The colours are often brilliant enough to catch the attention of the most casual observer, but at other times they can only be made out with the aid of dark; ...

    Notes: [Auszug] MR. WATSON asks, What is the physical evidence in favour of the existence of A, B, C, and α, β, γ ? With regard to the former the evidence, derived from the permanence of the magnetisation in a small piece of a hard steel magnet, seems to me almost conclusive; while the following consideration ...

    An Error in Maxwell's “Electricity and Magnetism” (1886)

    Notes: [Auszug] MANY of your readers will be aware that Maxwell (ii. § 544) deduces the equations of induction of currents from the laws of electro-dynamics with the aid of the principle of energy, using a proof taken from Helmholtz. I find that this proof is erroneous; and, as a point of considerable physical ...

    Notes: [Auszug] COLOURED rings are often seen surrounding the shadow of the spectator's head when the sun is shining on a fog of water particles. They are known by various names, such as glories, anthelia, Ulloa's rings, &c. Can any of your readers inform me if they can also be seen when the fog is frozen? ...
