What is parallex method |
|
Answer» Parallax\xa0is a method of measuring distance to an object. Similar to how our binocular vision helps us determine distance, the direction to a distant point is slightly different from two separate observation positions. The method where the position and direction of the object changes when we observe from some different position is called a parallex method . Let (N) is the near by star whose distance D from the earth is to be found F is far of star whose direction and position of earth in the orbital motion.When the earth is at A the parallax angle is (thita1) after six months the earth is at opposite position B the parallax angle become (thita2)(Thita)=(thita1)+(thita2)(Thita)=Parallex angle. |
