Briefly explain parallax method. Please some one answer my question. It\'s urgent? |
| Answer» Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Distance between the two viewpoints is called Basis.Similarly, α = d/DWhereα = angular size of the planet (angle subtended by d at earth) and d is the diameter of the planet.αis angle between the direction of the telescope when two diametrically opposite points of the planet are viewed. | |
