Page 286 - ON THE WIDENING OF SPECTRUM LINES. [Philosophical Magazine, Vol. xxix. pp. 274 — 284, 1915.] MODERN improvements in optical methods lend additional interest to an examination of the causes which interfere with the absolute homogeneity of spectrum lines. So far as we know these may be considered under five heads, and it appears probable that the list is exhaustive : (i) The translatory motion of the radiating particles in the line of sight, operating in accordance with Doppler's principle. (ii)...
Page 298 - H gauss causes the electrons to precess around the direction of the lines of force with angular velocity eH/2mc, where e and m are the charge and mass of the electron and c the velocity of light.
Page 509 - This elliptical path seemed to be a splendid example of a resultant of two simple harmonic motions at right angles to each other and differing in period by a small amount which could be easily calculated, or which could be determined experimentally.
Page 755 - Laplace's dynamical as on the equilibrium theory there is exact agreement (or exact opposition) of phase between the tidal elevation and the forces generating it, in the case of an ocean covering the globe or bounded by parallels of latitude, the depth being supposed either uniform or a function of latitude only. Observed conspicuous and varied differences...
Page 484 - There is as yet no experimental evidence to show whether the electric current is really a current of a material substance or a double current, or whether its velocity is great or ' Maxwell (ii. 482) incorrectly says : ' The quantity [<h— ?i] may be shown experimentally not to be always zero.
Page 451 - ... and it was usually supposed that the action was analogous to that of a violin bow, so that the vibrations were executed in the plane containing the direction of the wind. A closer examination showed, however, that this opinion was erroneous and that in fact the vibrations are transverse to the wind*. It is not essential to the production of sound that the string should take part in the vibration, and the general phenomenon, exemplified in the whistling of wind among trees, has been investigated...
Page 218 - ... veins which everywhere intersects the granitic rocks. These veins range from a fraction of an inch to 2 feet in thickness, but in the thicker veins there are numerous inclusions of the country rock. They are irregular in form, thickness, and direction, and are due to the intrusion of a basic magma which underlay the district. The author describes the microscopic characters of these tachylytes, and comments on their general glassy and cryptocrystalline nature, which he does not regard...
Page 848 - Beds into an upper and si lower series, owing to the absence of the Aymestry Limestone. They are composed mainly of sandy shales and sandstones above, and of sandy shales with layers of calcareous nodules or of calcareous bands below. Dayia navicula is a common fossil up to 240 feet from the top of the Ludlow Sliales, and...
