What is reverberation? Why is sound wave called longitudinal wave? If the distance of the object from the submarine is m then find the motion of the sound. A sonar device on a submarine sends out a signal and receives an echo A stone is dropped from the top of a tower m high into a pond of w One strikes the Explain how defects in a metal block can be detected using ultrasound Flash and thunder are produced simultaneously. When a sound is reflected from a distant object, an echo is produced. More General Science Questions Q1. Does sound follow the same laws of reflection as light does? Calculate the speed of sound in water if the distance of the object from submarine is 3, m.

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.
