How to use Line of sight in a sentence
The above are velocities transverse to the line of sight.
Fate's reflection moved into her line of sight.
Elisabeth and Connor were both out of Victor's line of sight.
Xander came into her line of sight then.
When the target is completely concealed it is necessary to lay the gun on an aiming point more or less out of the line of fire, or to lay on a " director " with a large amount of deflection, and to align aiming posts with the sights at zero to give the direction of the target, and afterwards perhaps to transfer the line of sight to some other distant object, all of which require a far greater scope of deflection than is afforded by the deflection leaf.Advertisement
The line of sight and the elevation of the gun henceforth are inseparable.
In 1868 he proved incandescent carbon-vapours to be the main source of cometary light; and on the 23rd of April in the same year applied Doppler's principle to the detection and measurement of stellar velocities in the line of sight.
The plane of the joint orbit, in which no deviation from circularity has yet been detected, nearly coincides with the line of sight.
This value of is the tangent elevation (T.E); the quadrant elevation (Q.E.) is -S, where S is the angular depression of the line of sight and if 0 is h ft.
In both cases no extraneous cause can be assigned; the period seems to be inherent in the star itself and not to be determined by the revolution of a satellite (no variability of the line-of-sight motion of Mira has been found, so that it is probably not accompanied by any large companion).Advertisement
Except when the line of sight is perpendicular to the plane of the orbit, the revolution of the two bodies will result in a periodic variation of the motion in the line of sight.
When the parallax of a star is known, we are able to infer from its proper motion its actual linear speed in miles per hour, in so far as the motion is transverse to the line of sight.
The velocity in the line of sight can be determined by spectroscopic observation, so that in a few cases the motion of the star is completely known.
Until the hypothesis has been thoroughly tested by an examination of the line-of-sight velocities of stars from the same point of view, this physical interpretation must be received with some degree of caution; but there can be no doubt of the reality of the anomalies in the statistical distribution of proper motions of the stars, and of these it offers a simple and adequate explanation.
It is clear that these results may give a simple key to some puzzling anomalies, and on the other hand, they may throw a measure of uncertainty over absolute determinations of line-of-sight velocities.Advertisement
This angle is measured by means of a graduated circle, rigidly attached to the tube of the telescope in a plane parallel to the line of sight.
When the telescope is turned in this plane, the angular motion of the line of sight is equal to that through which the circle has turned.
The angular motion of the telescope in passing from this position to that when the celestial object is in the line of sight is the distance (ND) of the body from the nadir.
The pitch of a steam-whistle quite obviously rises and falls as the engine to which it is attached approaches and recedes from a stationary auditor; and light pulses are modified like sound-waves by velocity in the line of sight.
This definition also makes optical depth proportional to the amount of obscuring stuff along the line of sight.Advertisement
To derive the stellar velocity in the line of sight relative to the observer it was then necessary to assume that the normal wave-lengths of the stellar and terrestrial spectra are accurately known.
The part of a star 's total velocity that is perpendicular to the line of sight is called the tangential velocity.
Seating can even be tiered on risers to provide optimum line of sight for all viewers.
If you have to trim the ending rows, don't let them fall in the center of the room or in the direct line of sight from an entryway.
My only complaint is that they won't notice Max until he's in line of sight of them, even where you're in the next room making all kinds of ruckus.Advertisement
Get closer to a window that has line of sight to the sky.
Part of the challenge, though, is that some satellite phones may require a better line of sight to the satellite in order for optimal operation.
You may need to place mirror on the an opposite wall to afford you this line of sight.
If the room dictates that your bed be placed so it's impossible to see who enters the room, place a mirror across from the door or on a wall that affords you a line of sight.
Separate By Season - Remove items that are inappropriate from the current season from your line of sight.
It was only possible to move the user's avatar along the line of sight.
