Frequency in sonar refers to the number of sound waves emitted per second. Higher frequencies provide better resolution and detail in detecting objects, but have shorter range and are absorbed more easily by water. Lower frequencies can travel long distances underwater, but have poorer resolution. The choice of frequency in sonar depends on the specific application and desired trade-offs.

What is the wavelength of sonar?
The wavelength of sonar waves can vary depending on the frequency of the sound waves being emitted. In general, the wavelength of sonar used in underwater applications ranges from a few centimeters to several meters. The selection of the frequency and corresponding wavelength is based on the specific requirements of the sonar system and the properties of the underwater environment being explored.
What are related words for ultrasonic?
Sonar, ultrasound, high-frequency sound.
What is the difference between Sonar and Ultrasound?
Sonar is a system that uses sound waves to detect objects underwater, while ultrasound is a medical imaging technique that uses high-frequency sound waves to visualize internal organs and tissues in the body. Sonar is typically used in underwater navigation and communication, while ultrasound is used in medicine for diagnostic purposes.
How was a diver killed by sonar technology?
A diver was killed by sonar technology when the high-frequency sound waves emitted by the sonar system caused internal injuries and disorientation, leading to a fatal accident underwater.
Can you hear the sound produced by sonar devices?
Sonar devices emit sound waves at frequencies that are typically beyond the range of human hearing, especially in the case of high-frequency sonar used for detailed imaging. However, some low-frequency sonar sounds can be audible to humans, particularly in certain conditions. The effectiveness of sonar relies on the reflection of these sound waves off objects underwater, which is then processed to provide information about the environment. Thus, while some sonar sounds may be heard, most are not audible to the human ear.
Why do narwhals communicate?
because they have high frequency sonar pings

What is the maximum frequency of a sonar before it effects wildlife?
The freqeuncy (or pitch) of the sonar is not generally the factor which is likely to effect wildlife, but the amplitude (how loud it is).
What is the difference between sonar and echo location?
Sonar location is in the water and echo location is in the air.
What does LFAS stand for?
Low Frequency Active Sonar
What are the three parameters of sound that can be measured by the SONAR?
Return timeAmplitudeDoppler frequency shift

Are pink dolphins and submarines the same because they use the same sonar?
Though they both use SONAR (SOund Navigation And Ranging) to navigate, submarines and marine mammals that use sonar are both very different in how they use it.Marine mammal sonar uses a much higher frequency than submarine active sonar systems transmit at. Also, submarines rarely use active sonar due to the fact it immediately gives away your location and range to an enemy. Marine mammals use their active sonar constantly to navigate through the water, communicate, and to find food, while passive sonar is the primary means of submarine navigation.Dolphin sonar sounds like a fast clicking sound, with occasional high frequency "squeals", similar to a dog toy, though at a much higher frequency range. The frequency is high enough that it must be demodulated by special equipment to a lower frequency to really hear it. Usually when submarines go to periscope depth, dolphins set off the torpedo warning alarms since their frequency is at a similar range. As a former Submarine Sonarman, I can also say that it also drives you nuts, especially when there's a whole group of them around the boat.
How is sonar different to vocal sounds?
Basically No difference at all. It only in the application that differences become apparent and useful.In practice Sonar uses high frequencies - which are still sound - because it allows resolving smaller and smaller objects and details as the frequency increases.You can use vocal sounds in the same way. Just ask a blind person.
