It highlights how bats and dolphins use echolocation with ultrasound for navigation and how sonar employs similar principles to locate underwater objects. Additionally, it covers ultrasonography, a medical imaging technique using harmless ultrasound waves for internal diagnostics. Overall, the page emphasizes the varied applications of ultrasound in nature and technology.
The distance to underwater objects can be calculated from the known speed of sound in water and the time it takes for the sound waves to travel to the object. If an ultrasound wave travels from the sh...The distance to underwater objects can be calculated from the known speed of sound in water and the time it takes for the sound waves to travel to the object. If an ultrasound wave travels from the ship to the submarine and back again in 2 seconds, what is the distance from the ship to the submarine? The sound wave travels from the ship to the submarine in just 1 second, or half the time it takes to make the round trip.
