The rate at which wave energy is dissipated in a damped medium is proportional to the frequency squared. That is, lower frequencies lose less of their energy to the medium they're propagating through, so their range is longer.
When sonar waves hit the floor, they bounce back to the device that emitted them. The sound it produces is typically a quick and distinct echo, which can help determine the depth of the water or the distance to the floor.
They could detect sound waves
because sound travels faster in water
That's because the buffer in you sound card is small so there is a need fot the sound card to wait before it can process all the sound samples. Either you can buy a better audio interface or you can try latency compensation in Sonar.
Sonar (or Sound Navigation and Ranging) is a type of technology that was designed to help with navigation, communication and locate objects underwater. Sonar projects sound waves then listens for the echo of the emitted sound waves to detect objects.
Scientists used a combination of echo sounders, sonar, and satellites to map the ocean floor. These technologies help create detailed maps by measuring the depth of the ocean floor and identifying features such as ridges, trenches, and seamounts.
Sonar is the science of sending out sound waves to an object and waiting for them to be bounced back to a receptor. Scientists can use this by shooting out the sound waves, then counting the amount of time it takes for the wave to shoot back to the receptor, and calculating the speed of the wave in proportion to the amount of distance traveled to get an idea of how large an object is. They would need to do so on all sides of it, of course, and it probably helps that they have lots of equipment to help measure.
SONAR (Sound Navigation and Ranging) primarily uses sound waves to detect and locate objects underwater, while satellites are employed for various complementary purposes. Satellites can provide critical data such as oceanographic conditions, surface features, and weather patterns, which enhance the effectiveness of SONAR operations. Additionally, satellite positioning systems like GPS help accurately determine the location of SONAR-equipped vessels, improving navigation and data collection. Thus, the integration of satellite technology enhances the overall efficiency and accuracy of SONAR applications.
SONAR was invented to detect underwater threats, such as submarines and mines, during World War I. It uses sound waves to detect objects underwater by emitting pulses of sound and listening for echoes. SONAR has since been used for various applications, including navigation, mapping the seafloor, and studying marine life.
If the police car is chasing you, the sound waves will have a higher frequency and intensity as it approaches you. As the police car moves away, the sound waves will have a lower frequency and intensity. This change in frequency and intensity can help you determine whether the police car is getting closer or farther away.
Sonar was used widely in World War II in an effort to locate enemy submarines. It wasn't as sophisticated as it is today, but it did help. Actual numbers are difficult to come by, but sonar was effective in the successful attacks on several submarines.
because the plants can not travel the sound at distance
