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 is the sound method of detecting things?
the method for detecting things with sound is called as SONAR-sound navigation and radiation. in this mehod we need to know the speed of sound in that medium. and as we have the relation that speed=distance*time, we can use a detector-to know that the sound that we sent has returned and stopcock to get the time. the distance we get should be divided by 2 so as to get the distance of the object from the source.
