Waves and the Earth - Sonar | Astrophysics | Physics | FuseSchool

In this video you are going to learn about sonar and how it helps us locate hidden objects.

You may have heard of the story of the Titanic, or even seen many of the Hollywood films which portray the tragic events of April 1912. It took a long time to locate the wreck: only in 1985. But how did we find out how deep it was under the surface of the Atlantic ocean?
