The two types of sonar are active and passive.
Active sonar uses a transmitter, a device that converts electrical energy to sound energy, to send out sound waves. The sound waves travel through the water until they strike an object. The object reflects them in various directions. Some of the reflected waves return to the sonar, where they strike a receiver. Sonar determines distances by measuring the time taken for a sound wave to travel from the transmitter, reflect from the object, and travel to the receiver.
Passive sonar receives sound waves given off by some other source, but does not transmit sounds. Passive sonar can therefore determine the direction of an object, but is not as effective as active sonar in determining its distance.
Hope I cleared your doubt!

What Types of waves are used in echolocation?
As the name suggests, sonar uses sonic waves (sound). Typically, sonars use sounds with frequencies inaudible to human ear.Another answer:Actually, sonar uses a wide range of frequencies. Very low frequencies (100 Hz to 1 kHz) are used for long range detection and deep sea floor sounding. Midrange frequences (1 kHz to 10 kHz) are used for target identification. Ultrasonic frequencies (50 kHz and up) are used in navigation and commercial sonar devices like fish finders.
How are sonar and radar different?
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
What is a system that uses multiple sonar devices?
Two or more sonar devices (transducers) could be set up in a sonar array of some sort. Multiple hydrophone setups are not uncommon in several applications.
How is a sonar and a echo different?
An echo is a sound wave reflecting off an object. Sonar is a means of detecting object using sound waves, usually echoes.
What are two different sources of energy that can be converted to electricity by a generator?
Two different types of energy are wind,and water.
What are the different type of sonar?
The two different types of sonar are passive and active.
What is sonar and how does it detect aeroplanes?
Sonar is the generic name of the technology that is used to locate objects underwater. Sonar systems are of two basic types - active and passive. In active sonar the system let's out a pulse of sound and then the operator listens for echoes. The passive sonar the operator listens to sounds emitted by the object one is trying to locate.

Which is correct grammar Two Different types or Two types?
Two types. By saying there are two 'types' you are already stating that there are 2 differentthings and so the word 'different' isn't necessary.

What are the two types of incubator?
There are two different types of incubators in relation to business. These types are the profit and non-profit incubators. Incubators can then be broken down and classified under these two types.
