Using specialised equipment, you send out a pulses of sound. You have a collecting device where the echoing sound is picked up. You can therefore work out how long sound takes to travel to the reflecting object and back to you. If you know the velocity of sound in the medium, you can work out the distance travelled by the sound in that time and so the distance to the object is half that distance.

ProfessorSonar is used to detect objects underwater by emitting sound pulses and measuring the time it takes for echoes to return. The data collected can be used to create images of underwater structures, map the seafloor, and locate objects or marine life. Sonar is commonly used in various applications such as underwater navigation, fisheries management, and oceanographic research.

Will using sonar kill you?
No, using sonar will not kill you. Sonar is a technology that uses sound waves to detect objects underwater and is commonly used in various applications such as navigation and fishing. It is safe for humans to use sonar equipment.
What things use sonar to see?
Some animals like bats and dolphins use sonar to see by emitting sound waves that bounce off objects and return to them, allowing them to "see" their surroundings. Submarines and ships also use sonar technology for navigation and detecting underwater objects.
How has sonar technology evolved from past to present?
Sonar technology has evolved from passive sonar systems used in World War I to active sonar systems that emit sound waves and detect their reflections. Modern sonar systems use advanced signal processing and computer algorithms for higher precision and improved target detection capabilities. Additionally, new developments in underwater acoustics have led to the use of multibeam sonar systems for mapping and imaging the seafloor with high resolution.
What is sonar commcation?
Sonar communication is a method of communication that uses sound waves underwater. Marine animals such as dolphins and whales use sonar to communicate with each other and navigate their surroundings. Sonar technology is also used by humans for underwater navigation, detecting objects, and communication in underwater environments.
How dangerous is it for divers when sonar is used in the water?
When sonar is used in the water, it can be dangerous for divers because the sound waves produced by sonar can disorient or harm marine life, including divers. The intensity and proximity of the sonar signal can impact the safety of divers, potentially causing injury or discomfort. Divers should be cautious and aware of sonar use in their diving areas to minimize risks.
