Which instrument is used to measure the depth of the ocean?

Content Curator

A Fathometer is an instrument used to measure the depth of the ocean or any other large body of water. It works by emitting a sound signal and measuring the time taken for the signal to travel to the bottom and back. The depth is then calculated based on the speed of sound in water and the time taken.

Fathometers are commonly used by ships, submarines, and oil rigs to determine the depth of the ocean for navigation and exploration purposes. Modern Fathometers use advanced technologies such as sonar and laser to accurately measure the depth of the ocean.

A fathometer is an instrument used to measure the depth of water in oceans, seas, lakes, and rivers.
It was first developed in the early 20th century and was commonly used on ships to map the sea floor and locate underwater objects.
The technology behind fathometers has improved over time, and today, they use sonar technology to measure depth.
Some modern fathometers can also measure water temperature and salinity, providing valuable information for oceanographers and marine biologists.
Fathometers are an important tool for navigation and safety at sea, as they help ships avoid underwater obstacles and make sure they don't run aground.

1.
If Bohr’s quantization postulate (angular momentum \( = \frac{nh}{2\pi} \)) is a basic law of nature, it should be equally valid for the case of planetary motion also. Why, then, do we never speak of quantization of orbits of planets around the Sun? Explain.

Two parallel plate capacitors X and Y are connected in series to a 6 V battery. They have the same plate area and same plate separation but capacitor X has air between its plates, whereas capacitor Y contains a material of dielectric constant 4. Calculate the capacitances of X and Y, if the equivalent capacitance of the combination of X and Y is \( 4 \, \mu\text{F} \). Calculate the potential difference across the plates of X and Y.
