    Sonar

    Learningpost, David Canavan, Published on 26/01/2010

    » I have a question for you, the answer to which I will give you at the end of this article. You are on a boat looking for a school of fish when your sonar finally finds a school. It emits a "ping" that travels at the speed of sound, which is about 1,500 metres per second in water, and the reflected sound is received half a second later. Using the formula distance equals to speed multiplied by time, work out how deep the fish are, but be careful - there is a catch (pun intended).
