Which of the following is correct? Parallax can only be used to find the distances to nearby stars, since measuring tiny parallax angles is very diffi- cult. Parallax can only be used to find the distances to far stars, since the method works better the smaller the paral- lax angle. Parallax refers to a law of geometry which states that the total arc length of a circle is 2tr. Parallax refers to the fact that electromagnetic radiation tends to move in straight lines. Parallax refers to the change in the position of an object as it rotates around another.
