Ence that any lava was emitted during this eruption.
It was allegedly her translator and emitted a low-level hum similar to the walls.
Soc.), regards the property as occasioned by internal vibrations within the molecule conditioned by a symmetrical double tautomerism, light of one wave-length being absorbed by one form, and emitted with a different wave-length by the other.
A yellowish glow emitted from some unseen light source in the grey walls reminded her of a late winter afternoon that never ended.
If each wave travels out from the source with velocity U the n waves emitted in one second must occupy a length U and therefore U = nX.
This transmitting plant was completed in December 1901, and Marconi then crossed the Atlantic to Newfoundland and began to make experiments to ascertain if he could detect the waves emitted by it.
Let a source of fluid be a point from which an incompressible fluid is emitted in all directions.
If all were still, the n waves emitted by S in one second would spread over a length U.
- Though a musical note has definite pitch or frequency, notes of the same pitch emitted by different instruments have quite different quality or timbre.
When the motion is upwards gas is emitted; when the motion is downwards it is checked.
Vapours are emitted which deposit sulphur and alum, and some mining is carried on.
The lava is emitted from the volcanic vent at a high temperature, but on exposure to the air it rapidly consolidates superficially, forming a crust which in many cases is soon broken up by the continued flow of the subjacent liquid lava, so that the surface becomes rugged with clinkers.
It was in vain that Groot emitted a Publica Protestatio, in which he declared that Jesus Christ was the great subject of his discourses, that in all of them he believed himself to be in harmony with Catholic doctrine, and that he willingly subjected them to the candid judgment of the Roman Church.
One important measurement is that of the wave-length emitted from an antenna.
They may be produced, by taking care, during the summer pruning or disbudding, to preserve a number of the little shoots emitted by the yearly wood, only pinching off the minute succulent points.
Kirchhoff in announcing that the lines of the spectrum were characteristic of the chemical substance which emitted them, and in indicating the value of this discovery in chemical analysis.
If we calculate from the total energy emitted, and not from the position of maximum intensity, the same result is obtained within a few degrees.
Tyndall used the dark rays from a luminous source, which are emitted in a highly concentrated form, so that it was possible to obtain a high temperature, which was, however, much lower than that of the source.
The usual bands were, however, temporarily effaced in the two brilliant apparitions of 1882 by vivid rays of sodium and iron, emitted during the excitement of perihelion-passage.
Certain to meet with many more species, some, as Ossifraga gigantea, as large as Albatrosses, and several of them called by sailors by a variety of choice names, generally having reference to the strong smell of musk emitted by the birds, among which that of "Stink-pot" is not the most opprobrious.
The Frenchman emitted a merry, sanguine chuckle, patting Pierre on the shoulder.
Dessalles slept propped up on four pillows and his Roman nose emitted sounds of rhythmic snoring.
If the particles were away, the wave would pass on unbroken and no light would be emitted laterally.
The light actually emitted laterally is thus the same as would be caused by forces exactly the opposite of these acting on the medium otherwise free from disturbance, and it only remains to see what the effect of such force would be.
The principle of energy makes it clear that the light emitted laterally is not a new creation, but only diverted from the main stream.
As regards the polarization of the dispersed light as dependent on the angle at which it is emitted, we find that although, when terms of the second order are included, the scattered light no longer vanishes in the same direction as before, the peculiarity is not lost but merely transferred to another direction.
Now 2 area 17r=2Xr; so that, in order to reconcile the amplitude of the primary wave (taken as unity) with the half effect of the first zone, the amplitude, at distance r, of the secondary wave emitted from the element of area dS must be taken to be dS/Xr (1) By this expression, in conjunction with the quarter-period acceleration of phase, the law of the secondary wave is determined.
The number of cercariae produced by the pullulating rediae in a single water-snail is immense, and as they are emitted at a given period or a few successive periods, the snail at these times appears enclosed in a cloud of whitish flocculent matter.
For our immediate purpose these considerations are of importance inasmuch as they bear on the question how far the spectra emitted by gases are thermal effects only.
Formerly, on the eve of a great eruption of Mauna Loa, this crater often spouted forth great columns of flame and emitted clouds of vapour, but in modern times this action has usually been followed by a fracture of the mountain side from the summit down to a point moo ft.
Lava streams are seldom emitted from these volcanoes, the material erupted consisting chiefly of ash and scoriae, which are spread over a very wide extent of country.
In the third, after the Campagna, by a great general uplift, had become a land surface, volcanic energy found an outlet in comparatively few large craters, which emitted streams of hard lava as well as fragmentary materials, the latter forming sperone (lapis Gabinus) and peperino (lapis Albanus), while upon one of the former, which runs from the Alban Hills to within 2 m.
Becquerel's observation in 1896 that certain uranium preparations emitted a radiation resembling the X rays observed by Rntgen in 1895.
The two leading types of volcanic areas are the plateaus, in which sheets of porphyrites, basalts and even trachytes were emitted, sometimes with wide discharge of volcanic ashes, and the puys, or isolated vents, or scattered groups of vents, which discharged comparatively a small amount of lava and ashes.
In 1684, while Perth, and his brother, Melfort, who went over to Rome, were in power, Renwick emitted an " Apologetical Declaration," in which the active enemies of his sect were threatened with secret trials and with assassination (October), and a " curate," with some soldiers, was murdered.
Heis the numbers and magnitudes of stars between the north pole and a circle 35° south of the equator are: - From the value of the light-ratio we can construct a table showing the number of stars of each magnitude which would together give as much light as a first magnitude star, viz.: - Comparing these figures with the numbers of stars of each magnitude we notice that the total light emitted by all the stars of a given magnitude is fairly constant.
National budgets are to be discriminated (r) as budgets passing under parliamentary scrutiny and debate from year to year, and (2) budgets emitted on executive authority.
Ozone is also emitted by a violet fluorspar from Quincie, dep. Rhone, France.
But when light is transmitted through a material medium, it always suffers some loss, the light energy being absorbed by the medium, that is, converted partially or wholly into other forms of energy such as heat, a portion of which transformed energy may be re-emitted as radiant energy of a lower frequency.
Since the rays used by Tyndall in these experiments are similar to those emitted by a heated body which is not hot enough to be luminous, it might be thought that the radiation, say from a hot kettle, could be concentrated to a focus and employed to render a small body luminous.
In addition to the above facts of polarization mention may be made of the partial polarization, in a plane perpendicular to that of emission, of the light emitted in an oblique direction from a white-hot solid, and of the polarization produced by diffraction.
The rays emitted from an axial object-point are not combined into one image-point by an ordinary biconvex lens of fixed aperture, but the central rays come to a more distant focus than the outer rays.
If at first the members of the council thought that Kutuzov was pretending to sleep, the sounds his nose emitted during the reading that followed proved that the commander-in-chief at that moment was absorbed by a far more serious matter than a desire to show his contempt for the dispositions or anything else--he was engaged in satisfying the irresistible human need for sleep.
The aromatic and irritating fumes emitted by burning amber are mainly due to this acid.
Ramsay, repeating these experiments, found that the inert gas emitted refused xIIl.
The dust emitted from mining the ore was poisonous in its raw state.
