Main
Differentiate between true meridian and magnetic meridian.
Answer
The true meridian is the line passing through the geographic North and South poles, representing the true north direction. The magnetic meridian is the direction indicated by a freely suspended, balanced magnetic needle unaffected by local attraction, representing the magnetic north.
With help of neat sketch explain about bubble line.
Answer
The bubble line (or axis of the bubble tube) is an imaginary line tangential to the longitudinal curve of the bubble tube at its center point. When the bubble is centered, this line is perfectly horizontal. In a sketch, it appears as a horizontal line passing through the center of the air bubble, perpendicular to the vertical axis of the instrument, ensuring the leveling of the survey equipment.
