This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Field Astronomy – Zenith Telescope”.
1. Which of the following indicates the use of Zenith telescope?
a) Zenith placement
b) Zero error
c) Low precision
d) High precision
View Answer
Explanation: Zenith telescope is used in case of obtaining high precision in the measurement of star positions. It involves the simplification of telescope construction. The actual purpose of designing it involves in the management of zenith.
2. Zenith telescope also known as __________
a) Zenith sector
b) Sextant
c) Zenith horizon
d) Azimuthal telescope
View Answer
Explanation: A zenith telescope can also be determined as zenith sector, which is capable of employing azimuth, fitted with levelling screws. The eye piece is fitted to micrometer along with levels.
3. Which of the following describes the usage of zenith telescope?
a) Determination of equator
b) Determination of earth poles
c) Determination of tropic of Capricorn
d) Determination of tropic of cancer
View Answer
Explanation: A zenith telescope is used in the determination of earth poles. It is a general usage of any type of zenith telescope adopted but zenith telescope is also able to determine the precise measurement of star positions.
4. Large zenith telescope is having a diameter of range ___________
a) 0.5-2m
b) 1-2m
c) 2-2.5m
d) 3-4m
View Answer
Explanation: Generally, zenith telescope is having a diameter of 3m aperture. But in case of large zenith telescope it is adopted with 6m diameter aperture which is capable of recording the minute measurements without error.
5. Zenith telescope has been replaced by ___________
a) Celestial telescope
b) Astronomical telescope
c) Radio astronomical quasar
d) Abnormal telescope
View Answer
Explanation: Though zenith telescope is capable of providing the required information, it is an old age method. In modern technique, radio astronomical quasar is adopted which can acquire information within minutes.
6. Zenith telescope can track the points other than its line of sight.
a) True
b) False
View Answer
Explanation: Zenith telescope is only capable of tracking the points which are present in its line of sight. Other points can be tracked by the present modern techniques which require skill for accessing.
7. Large zenith telescope is used at ___________
a) Australia
b) India
c) South America
d) North America
View Answer
Explanation: Due to the high end technological usage and vast information obtained from zenith telescope, the usage is done at very limited placed. It is widely used in North America region, as researches are being conducted in a huge manner. It is opted as the third largest optical telescope.
8. Which of the following indicates the objective of the zenith telescope?
a) Spectral energy consumption
b) Spectral energy dissolution
c) Spectral energy distribution
d) Spectral energy reflection
View Answer
Explanation: The main objective of the zenith telescope involves in spectral energy distributions and red shifts over numeral galaxies. This might help in determining the supernovae which is at a distant place.
9. Zenith telescope is more expensive.
a) False
b) True
View Answer
Explanation: Zenith telescope liquid mirror will cost about 1% of the general telescopic mirror. This may help in its economical point of view, but in terms of work it might lag behind in some aspects.
10. Who among the following theorized zenith telescope for the first time?
a) Sir Isaac Newton
b) Albert Einstein
c) Ramanujan
d) Faraday
View Answer
Explanation: Sir Isaac Newton was the first person to theorize the zenith telescope but couldn’t build it because of the fact that he is not able to control the speed of rotation of the liquid present in it.
