What is the name of the device that is used to see objects on the surface from submarine?
periscope, optical instrument used in land and sea warfare, submarine navigation, and elsewhere to enable an observer to see his surroundings while remaining under cover, behind armour, or submerged.
Which device is used to see objects underwater?
Sonar uses sound waves to ‘see’ in the water. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself. There are two types of sonar—active and passive.
What is a marine sextant?
The sextant is an instrument used to measure angles. Mainly used at sea, the tool is so named because its arc is one-sixth of a circle – 60 degrees. Sextant is an essential tool for celestial navigation and is used to measure the angle between the horizon and a visible object (or two objects at sea.
What is the name of scientific instruments?
General Knowledge – Scientific Instruments
| Instrument | Use |
|---|---|
| Ammeter | Measures electric charges |
| Anemometer | Measures wind speed |
| Barometer | Measures atmospheric pressure |
| Bolometer | Measures electromagnetic radiation |
What instrument is used to see objects on the surface?
periscope
The correct answer is the periscope….Detailed Solution.
| Instrument | Used |
|---|---|

| Altimeter | Used in aircraft to measure altitudes |
Which instrument is used to see objects at the surface of water from a submarine underwater?
For seeing objects at the surface of water from a submarine under water, the instrument used is periscope.
Is used to look at things which are far away?
Telescopes make distant objects such as planets and stars seem bigger and closer. The optical telescope is the most common type. Just like our eyes, this telescope makes use of light.
What is the error of perpendicularity?
The error of perpendicularity: is produced by the index glass not being perpendicular to the plane of the instrument. If they appear in alignment, the error of perpendicularity is not present. If not, turn the first adjustment screw at the back of the index glass, until they appear in alignment.
What are the uses of sextants?
Sextant, instrument for determining the angle between the horizon and a celestial body such as the Sun, the Moon, or a star, used in celestial navigation to determine latitude and longitude.
What do you mean by scientific instruments and objects?
A scientific instrument is a device or tool used for scientific purposes, including the study of both natural phenomena and theoretical research.
What instrument do scientists use to observe space?
The Hubble Space Telescope has three types of instruments that analyze light from the universe: cameras, spectrographs and interferometers.
