SONAR
1. A system using transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distance to the floor of a body of water.2. An apparatus, as one in a submarine, using sonar.3. Echolocation.http://www.thefreedictionary.com/sonar
the light that is reflected by that object.
Yes. That's exactly the process used by those expensive "noise-canceling" headphones that do such a great job when you want to listen to your CD on an airplane.
An echocardiography is used in the diagnosing and follow-up with people who are believed to have heart disease. It is the process of using sound waves to take a picture of the heart.
By creating an xray using sound waves.
The same way we do - by using their ears ! Bats use ultra-sonic sound which is higher than the range humans can hear - their 'squeaks' bounce off objects, and prey and are reflected back to the bat so it can navigate in total darkness.

Photography is the process of producing images using reflected light.

Finding out what objects are in a body of water by using sound waves.
Not all sound that hits matter is absorbed. Some of it is reflected. That means sound bounces off the solid matter the way a tennis ball bounces off a wall. Sound reflected back to its source is an echo.
