Ultrasonic waves can be used to produce images of objects inside the body. The sound waves are partially reflected when they reach a boundary between two materials of different densities. They use ultrasonic waves to see the baby before birth.

Ultrasonic waves are used to reflect within an object to create an image of what is within that object. It is commonly used to see things within the human body for finding a problem that might result in surgical actions. BUT it is most commonly used for seeing the development of a baby within a womb. THE END

Such imaging is possible because sound waves are partially reflected when they reach a boundary between two materials of different densities. We use this techonology in ultrasounds. You are able to see the baby inside the mother.

We use these waves to view things inside of an object. They are mainly used to see babies in the womb. These ultrasound waves are sound waves with very specific frequencies so that they can view a baby properly. Then the waves bounce off it and create an image in the computer.

Ultrasonic waves are waves above 20,000 Hz. These images are possible because they can relfect off a bondery between two materials. We use this to observe fetuses.
