Which type of wave is used in sonar to detect objects'(1 point) electromagnetic sound water seismic

## Step 1<br />Sonar, short for Sound Navigation and Ranging, is a technique that uses sound propagation to navigate, communicate with, or detect objects on or under the surface of the water. <br /><br />## Step 2<br />Sonar is used by animals such as bats and dolphins for navigation and hunting. <br /><br />## Step 3<br />Sonar systems are also used in ships and submarines to detect other vessels and obstacles. <br /><br />## Step 4<br />Sonar systems operate by emitting a sound wave that travels through the water. When this wave encounters an object, it is reflected back to the sonar system. <br /><br />## Step 5<br />The time it takes for the wave to return gives an indication of the distance to the object. <br /><br />## Step 6<br />Given the options, the type of wave used in sonar to detect objects is sound.
