    Propagation of Sound and Light in an Irregular Atmosphere (1918)
    [s.l.] : Nature Publishing Group
    Nature 101 (1918), S. 284-284 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] I SUPPOSE that most of those who have listened to (single-engined) aeroplanes in flight must have noticed the highly uneven character of the sound, even at moderate distances. It would seem that the changes are to be attributed to atmospheric irregularities affecting the propagation rather than ...

    The Glow in Photoelectric Cells (1932)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] MAKERS of photoelectric cells usually state the limits of e.m.f. which can be used, and beyond which a glow discharge sets in. Although I have not met with any explicit statement, it seems to be implied that short of this e.m.f. no glow is visible. Recently, when using a 'Madza' thin film ...

    Notes: [Auszug] MUCH has been written on the various band-series and isolated bands in the spectrum of mercury, and their relation to the atomic excited states : but it cannot be said that the subject has been satisfactorily cleared up. I wish here to record an observation which will help to decide ...

    Notes: [Auszug] MANY years ago it was found that the mineral beryl often contains much more helium than can be accounted for by the traces of uranium and thorium which are present1. Recently returning to the subject, I have examined some thirty-five or forty beryls from different parts of the ...

    Notes: [Auszug] MERCURY vapour of low pressure stimulated by the resonance line λ2537 emits fluorescent light for a time of the order of 10−3 sec. This allows the fluorescence, when generated in a moving current of vapour, to travel away from its place of origin. The fluorescent light shows a ...

    Notes: [Auszug] IT was found by Füchtbauer1 that mercury vapour of low density, illuminated by the radiation of a mercury arc, emits all the chief lines of the mercury spectrum in fluorescence. These experiments were extended by R. W. Wood,2 who found, in accordance with the views ...

    Notes: [Auszug] IN a letter published under the above title in NATURE of May 2, it was stated that the series of bands which appear in absorption of the unexcited vapour in the region from λ2943 to λ2614 could be obtained in fluorescent emission by exciting with the iron arc in the region on the long wave side ...

    Notes: [Auszug] SOME years ago I found a long series of diffuse bands from λ2943 to λ2614 in the absorption spectrum of a long column of mercury vapour.1 The same series was found independently and about the same time by Mohler and Moore. Up to the present, these bands have never been ...

    Double Refracting Structure of ‘Corex’ Glass. (1930)

    Notes: [Auszug] SOME years ago I found that silica glass showed a doubly refracting structure (Proc. Roy. Soc., A, vol. 98, p. 284 ; 1920. Also Proc. Optical Convention, Part 1, p. 41; 1926). This structure is quite distinct from any due to bad annealing, and seems kindred to the ‘liquid crystals’ of Lehmann. ...

    Notes: [Auszug] A BAND in the mercury spectrum referred to as 2540 has been the subject of much discussion, owing to its proximity and apparent relationship to the resonance line 2536.52, and to the fact that it is seen in absorption by unexcited mercury vapour of suitable density. I have long suspected that ...
