Lengths
Angles
Heights
All of these
Answer is Right!
Answer is Wrong!
The correct answer is: D. All of these
In field astronomy, the quantities observed are entirely lengths, angles, and heights.
- Lengths are used to measure the distances between objects. For example, the distance between two stars can be measured by using the parallax method.
- Angles are used to measure the positions of objects relative to each other. For example, the angle between two stars can be measured by using a sextant.
- Heights are used to measure the elevations of objects above a reference level. For example, the height of a mountain can be measured by using a clinometer.
All of these quantities are important in field astronomy because they allow astronomers to determine the positions, distances, and sizes of objects in space.
