Sure. When the sound from a sonar emitter is bouncing off a surface, the time it takes to bounce back is related to the distance of the surface from the emitter. The amount of time that the sound is traveling is related to the speed of sound. We use a simple formula that can be calculated. If the emitter is in a stationary location, we just multiply the distance by the speed of sound

who created sonar?

The first person to use sonar was the American engineer and inventor Robert Watson-Watt in 1909. It is named after the sound which it emits, but it is also related to the word “sounder” which is short for “sounding instrument.” So we can say that the sound of the sonar is the first sound we hear when using sonar.
