ıraklık açısı

Turkish - English

Definition of ıraklık açısı in Turkish English dictionary: parallax; The change of angular position of two stationary points relative to each other as seen by an observer, due to the motion of an observer; The change in the position of an object in the heavens due to the orbit of the earth Observable parallax in the fixed stars is a proof of the rotation of the earth around the sun Explanatory Diagram; Parallax is when an object appears to change its position because the person or instrument observing it has changed their position. Difference in the direction of a celestial object as seen by observers from two widely separated points, a measurement used to find a body's distance. The two positions of the observers and that of the object form a triangle; its apex angle (at the object) is twice the parallax, which becomes smaller with increasing distance. Observations for calculating the Sun's parallax can be made simultaneously from two different places on Earth's surface; that value reaches a maximum of 8.794 seconds of arc for observers at points separated by Earth's diameter. Observing the difference in an object's position as seen from Earth at points six months apart in its orbit (stellar, or annual, parallax) allows measurements of distances (e.g., of stars) too large to be made from two places on Earth's surface. The nearest star system, Alpha Centauri, has a stellar parallax of 0.76 second of arc. Highly precise parallaxes, and thus the positions, of more than 100,000 stars in the Sun's vicinity were determined from data collected by the European Space Agency's Hipparcos satellite (launched 1989); With a lens-shutter camera, parallax is the difference between what the viewfinder sees and what the camera records, especially at close distances This is caused by the separation between the viewfinder and the picture-taking lens There is no parallax with single-lens-reflex cameras because when you look through the viewfinder, you are viewing the subject through the picture-taking lens; Angular displacement in the apparent position of a celestial body when observed from separated points; an apparent shifting of an object's position resulting from observing the object from two different vantage points Stellar parallaxes are seen when we view nearby stars from opposite sides of the Earth's orbit; The difference in appearance or position of an object when viewed from two different locations; the difference in apparent direction of an object as seen from two different vantage points; The apparent angular displacement of an object as seen in an aerial photograph with respect to a point of reference or coordinate system Parallax is caused by a difference in altitude or point of observation; the apparent displacement of an object as seen from two different points that are not on a line with the object; Parallax is the effect that nearby objects seem to move relative to far-away objects when you move to another viewpoint The parallactic angle is the angle over which the nearby object seems to move relative to the background In astronomy, the maximum parallactic angle of a star due to the motion of the Earth in its orbit around the Sun is called the star's parallax Because stars are very far away, their parallaxes are very small: the nearest star has a parallax of only 0 76 arcseconds; The difference between what the viewfinder sees and what the camera records Typical of lens/shutter cameras and is caused by a separation of the viewfinder and the picture taking lens (ie the user is not viewing the image through the picture taking lens); An effect seen in close-up photography when the viewfinder is offset by some distance from the lens The scene through the viewfinder is offset from the scene through the lens; The difference in point of view that occurs when the lens (or other device) through which the eye views a scene is separate from the lens that exposes the film; The apparent shift of an object against a background due to a change in observer position; parallaxis = [Greek] change Parallax is the effect that nearby objects seem to move relative to far-away objects when you move to another viewpoint For instance, if you hold your finger in front of your nose and look at it with just one eye at a time (without moving your finger), then you'll notice that your finger blocks different parts of the background depending on which eye looks at it The parallactic angle is the angle over which the nearby object seems to move relative to the background In astronomy, the maximum parallactic angle of a star due to the motion of the Earth in its orbit around the Sun is called the star's parallax Because stars are very far away, their parallaxes are very small: the nearest star has a parallax of only 0 76 arcseconds; The apparent difference in position of a body (as the sun, or a star) as seen from some point on the earth's surface, and as seen from some other conventional point, as the earth's center or the sun; An optical illusion that causes a viewed image to apparently change position as the viewer's eye moves to either side of the eyepiece; The difference in appearance in an object when seen from different perspectives The parallax between left and right eye views produces 3-D perception Holograms are unique in providing a wide, continuous range of parallax on the image
