Yes, that's the way it works. A parallax angle of 1" (arc-second) means that the object is at a distance of 1 parsec (that's how the parsec is defined); at a parallax angle of 1/10 of an arc-second, the object would be at a distance of 10 parsec, etc. A parsec is approximately 3.26 light-years.

What are advantages of morphing technology?
morphing is a Technic for photography world advantage to shift images media from one object to others can make a lot of changes.
What is the effect of carrier frequency variation on AM signal?
If the modulation is to large your bandwidth will be to wide in other words the frequency shift will be larger than normal that will result in a distorted audio signal at the receiver
What is the meaning of second shift?
The second shift is a woman's "shift" of work at home, consisting of housework. (The "first shift" being their job.)
How do the arithmetic shift and logical shift differ?
With a logical shift the vacated bits are always filled with zeroes. With an arithmetic shift, a left shift will fill vacated bits with zeroes but a right shift fills the vacated bits with a copy of the most significant bit.
How are radio waves used to find the speed of a moving object?
By using an phenomenon called the Doppler Effect, which causes waves (e.g. radio, light, sound) that are reflected off a moving object (or emitted by a source on a moving object) to shift frequency proportionally to the speed of the object.if the object is moving towards the observer the waves shift to a higher frequencyif the object is moving away from the observer the waves shift to a lower frequencyThe speed detector (e.g. RADAR gun) uses a method called heterodyning to "beat" the original transmitted radio waves with the received radio waves that reflected back from the object to generate a "difference frequency" that will be proportional to the relative speed of the object to the observer. This "difference frequency" is then fed to a frequency counter circuit and the result is scaled to be displayed in the correct units of speed that the user needs. For objects that emit the waves themselves (e.g. stars, galaxies) it is necessary to find spectral lines of known elements or compounds and measure how much the frequency of these spectral lines have shifted from their known standard frequency. If sound waves emitted by a vehicle (e.g. train whistle) you must somehow know the frequency of the sound source on the vehicle when it isn't moving (this may or may not be possible).
How does parallax shift varies with distance?
The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.
What is higher for closer stars A absolute magnitude B red shift C parallax D blue shift?
The answer would be C) Parallax.The Absolute Magnitude of a star is the star's actual brightness, and is therefore not dependent upon the position of the observer.Red Shift and Blue Shift are consequences of a stars speed relative to the observer. Again this is independent of the stars proximity to the observer.Parallax, is the apparent change in position based upon the motion of the observer, and is directly proportional to the proximity of the object. Just as, when driving on the road distant trees or buildings don't appear to zoom past you as quickly as a pedestrian on the side of the road, so it is with stars. The closer they are the larger the parallax is as the Earth orbits the Sun, for example.
What is The apparent change in position of an object with respect with respect to a distant background is called?
Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
What is a parallax error?
Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
What increases as an object comes closer to an observer?
red shift i think
What is the apparent shift in measurement is called?
parallax
Does a red shift means that are moving closer to earth?
No. A red shift indicates that the object is moving away from the earth.
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
What is it called when the apperent shift in the position of an object when viewed from two locations?
Parallax is the apparent difference in the position of a nearer object, compared to more distant background objects, when viewed from two different positions.
How can parallax be used to determine the distance to nearby stars?
The reciprocal of the parallax is taken. For example, if the stellar parallax is 1 second, the distance is 1/1 = 1 parsec; if the parallax is 0.1 second, the distance is 1/0.1 = 10 parsecs, etc.
What is the apparent shift of stars as earth orbits the sun?
parallax :)
What is a star's apparent shift in motion called?
Motion parallax.
