H E Edgerton, improved greatly on the stroboscope and this was made widely available by General Electric. Strobes had been invented more than a hundred years earlier in Belgium.

He then went on to improve sonar, by introducing the element of 'side-scan' sonar, with which many pictures of the ocean floor are made. These have much more resolution and display than 'ping' sonar.

What uses sound waves to find things under water?

Sonar technology uses sound waves to find objects under water by sending out sound pulses and measuring the time it takes for the signals to bounce back. By analyzing the returning echoes, sonar systems can determine the distance, size, and shape of underwater objects.

How do you measure volume of myself?

you need to fill a bath half full. then get into the bath and go under the water. the resultant height change in the water level will reflect you volume. I would suggest that you remain under the water for at least 10mins to allow the water surface level to stablise
