Sonar frequencies typically range from around 20 kHz to several hundred kHz. Lower frequencies can travel long distances in water, but higher frequencies provide better resolution for detailed imaging. The choice of frequency depends on the specific application and environmental conditions.

What is SONAR frequency range?
SONAR uses frequencies typically ranging from 10 kHz to 100 kHz for underwater communication and detection. The frequency used depends on factors such as the depth of the water being surveyed and the desired resolution of the SONAR system. Lower frequencies like 10 kHz are used for deep water surveying, while higher frequencies like 100 kHz offer better resolution for shallower depths.
What difference does frequency have in sonar?
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.
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.
What Types of waves are used in echolocation?
Sound waves are typically used in echolocation. Animals emit high-frequency sound waves that bounce off objects in their environment and return to them as echoes, allowing them to determine the location, size, and shape of objects. Bats, dolphins, and some species of birds are known to use echolocation.
When was the sonar invented by Lewis Nixon?
Lewis Nixon did not invent sonar. Sonar was actually invented by Reginald Fessenden in 1913. Sonar stands for sound navigation and ranging, which is a technique that uses sound propagation to navigate, communicate with, or detect objects underwater.

Can a sonar machine identify the object showing up on the sonar?
Sonar (which stands for SOund NAvigation and Ranging) can be made to identify the object it pings on - if active sonar; if passive sonar, identify the object making the sound it picks up. The higher the frequency of the active sonar ping, the better the resolution - but the shorter the range. At higher resolutions, it is not hard for the sonar to identify the object it pings on. At lower frequencies, the range is greater but it is harder for the sonar to identify what is being pinged. Another benefit of active sonar is the range and direction of the target can be discerned. Passive sonar just listens to the ambient water. Identification of the sound source can be made if the frequencies of the target making the sound are known and identified in a database. One problem with passive sonar is that it is hard to know the range of the target making the sound, although the direction will be known. Water temperature and depth have a great effect on sonar, so this must be taken into account when calculating distance. Sonar is used in the Military, Geological Surveying, and the Medical field.
What is sonar frequency?
The frequencies on which sonar is used vary widely. Human hearing is usually cited as ranging as from 20 cycles per second (Hertz) to 20,000 cycles per second. There are many sonars that use frequencies in the 20 to 20,000 Hertz range. In general, the sonars that are used for short range underwater applications operate on a slightly higher frequency than those that are designed to look over long distances. But there are a lot of sonars which use frequencies far outside the range of human hearing. Medical imaging is the most popular use of sonar. The range of frequencies used by these devices range from 2 million cycles per second to 18 million cycles per second. These frequencies are far above what humans can hear.
Form of sonar used to locate enemy submarines by ultrasonic waves?
Due to their short ranges, ultrasonic (>20khz) frequencies aren't used for ship or submarines' primary Active Sonar systems. Though the actual frequencies used are classified, I can say that they're nowhere near the ultrasonic range. Submarines do employ ultrasonic frequency detection systems that are passive sonar based, but they're primarily for detecting active sonar from homing torpedoes. They're also annoying for detecting any bottle-nosed dolphins in the area when you're at Periscope Depth.

Is there such thing as sensors that pick up ultrasonic frequencies?
Yes there is. They're commonly known as sonar sensors. Sonar sensors are usually a coupled device which emitt and receive high frequency sound waves and can be used to detect objects within a close proximity.
