Sound Navigation And Ranging - Sonar

Sonar

A sonar device sends sound waves into ocean water in order to determine the distance of a reflecting object in the ocean. If it takes 3 secs for the sound wave to make a round trip from the sonar device, how far down in the ocean is the object if the speed of sound in ocean water is 1530 m/sec?

The strings: S₇P₄A₄₄ (Motion - Oscillatory Motion).

The math:
Pj Problem of Interest is of type motion (oscilatory).

Sonar

SONAR is the acronym for Sound Navigation And Ranging. A sonar device is often used to detect the location of matter able to reflect sound waves. When a sonar device sends sound waves, the reflecting object reflects the waves back at the same speed if the medium is the same. By timing the time for the wave to return, the total distance traveled can be calculated.

So, Total distance traveled by sound wave = speed x time
So, total distance traveled = 1530 x 3 = 4590 meters
Total distance is twice the distance from sonar device to object
So, distance from sonar to reflecting object = 4590/2 = 2295 meters.

Math

The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
