Question
What is parallax angle?
✓
Answer
i) Angle between the two directions along which a star or planet is viewed at the two points of observation is called parallax angle (parallactic angle).
ii) It is given by $\theta=\frac{b}{D}$
where, b = Separation between two points of observation.
D = Distance of source from any point of observation.
ii) It is given by $\theta=\frac{b}{D}$
where, b = Separation between two points of observation.
D = Distance of source from any point of observation.
