Question
Write down the applications of echo?

Answer

Applications of echo:
  • Some animals communicate with each other over long distances and also locate objects by sending the sound signals and receiving the echo as reflected from the targets.
  • The principle of echo is used in obstetric ultrasonography, which is used to create real – time visual images of the developing embryo or fetus in the mother’s uterus. This is a safe testing tool, as it does not use any harmful radiations.
  • Echo is used to determine the velocity of sound waves in any medium.
