Explain. Parallax: When the two objects are seen on a straight line, they seem to be concident. If the objects are at different places and the eye is moved side ways then there is a relative displacement between them. The nearer object moves in the opposite direction while the further object moves in the same direction of eye.
Parallax is a method of using two points of observation to measure the distance to an object by observing how it appears to move against a background. One way to understand parallax is to look at a nearby object and note its position against a wall. If you look with just one eye, then the other, the object will appear to move against the ...
(i) Parallax Method: When an object is seen by closing our right and left eye alternatively, there is a shift in the position of the object w.r.t. the background observed. This is known as parallax. Imagine an object P placed at a distance x from our eyes.
Assertion: Parallax method is used for measuring distances of nearby stars only. Reason: With increase of distance of star, parallactic angle becomes too small to be measured accurately. View Solution
Assertion :Parallax method is used for measuring distances of nearby stars only. Reason: With increase of distance of star, parallactic angle becomes too small to be measured accurately. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Parallax observed from two positions ‘a’ and ‘b’. Let the angle subtended by the arc-ab at O be = P. Imagine a circle that has its centre at O and passes through A and B. Then from the definition of an angle, we can write. P = [length of arc ‘AB’]/ [radius of the circle (OA or OB)] If we know any two variables in the above equation ...
Explain parallax method for measuring distance of a nearly star. Solution. Verified by Toppr. The distnace can be measured by measuring the parallax angle θ. It is subtended by the distant astronomical object at the two locations on the earth separated distance b. Thus, θ = b d where d be the measuring distance. Was this answer helpful?
Star A is farther than star B. Which star will have a large parallax angle? View Solution. Q 2. A star has a parallax angle p of 0.723 arcseconds. What is the distance of the star? View Solution. Q 3. You measure the parallax angle for a star to be $$0.1$$ arcseconds.
43. The parallax of distant planet as measured from two diametrically opposite ends of earth is 1 minute. The distance of planet from the earth is (Given radius of earth = 6400 km) (1) 6.8 1010 m ((2) 4.4 1010 m (3) 2.2 x 1010 m (4) 8.4 x 108 m 24. In the absence of external force, which of the Clin nuantities must remain conserved?
The parallax of a far off planet as measured from the diametric extremes of the equator of the Earth is 2.0minutes. If the radius of Earth is 6400 km, find the distance of the planet from the Earth. View Solution
