The principle of 'parallax' in section 2.3.1 is used in the determination of distances of very distant stars. A star which has a parallax 1 arcseconds is at a distance of 1 parsec, which is equal to 3.26 light years. Star b has large parallax angle. With increase of distance of star, parallactic angle becomes too small to be measured accurately. When the two objects are seen on a straight line, they seem to be concident. Explain the parallax method for measuring large distances. If the objects are at different places and the eye is moved side ways then there is a relative. A man is trying to start a fire by focusing sunlight on a piece of paper using an equiconvex lens of focal length 10 cm.
A Star Which Has A Parallax 1 Arcseconds Is At A Distance Of 1 Parsec, Which Is Equal To 3.26 Light Years.
There is an hinverse relation between star's parallax and its distance. Explain the parallax method for measuring large distances. The principle of 'parallax' in section 2.3.1 is used in the determination of distances of very distant stars.
Assertion :Parallax Method Is Used For Measuring Distances Of Nearby Stars Only.
As near to the scale of the ruler as possible and the eye must be directly above the scale as far. If the objects are at different places and the eye is moved side ways then there is a relative. Hence, d = 1 0.723= 1.38parsecs
When The Two Objects Are Seen On A Straight Line, They Seem To Be Concident.
The diameter of the sun is 1.39×109m and its mean distance from the. Because in parallax method, the far star or any other object has less parallax angle and the close star has large parallax angle.

Relationship Between A Star's Distance And Its Parallax Angle:
D = 1 p explanation: D = 1 p the distance d is measured in parsecs and the parallax angle pis measured in arcseconds. The baseline ab is the line joining the earth's two locations six months apart in its orbit.
To Minimise Parallax Error, The Observer Should Place The Object :
With the help of it, explain the method to determine the shape of a heavenly body. With increase of distance of star, parallactic angle becomes too small to be measured accurately. Star b has large parallax angle.
