Speed of sound is highest in which medium?

Submarine Sonar in a nutshell, is a technology that allows submarines to see underwater. It is achieved by emitting sound waves and listening to their echoes. This principle is called the echolocation which is the same as the bats which locate via air. When a sound wave that is emitted by the sonar system encounters an object in the water, some of the wave bounces back as echoes. By analyzing the time taken for the echo to return and by the characteristics of echo, submarines can determine the distance, size and even the type of object that was found. Sound waves have unique properties and that properties vary depending on the environment. Unlike air, water is an excellent conductor of sound, with sound traveling at a much higher speed in water. With sound traveling in air at around meters per second and sound traveling in water at 1, meters per second, this phenomenon becomes crucial for the effectiveness of the sonar operations. The Sonar system typically consists of transducer, which are devices that both emit and receive sound waves.
