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).
