them reflect back from things better than normal sound waves.
2. In medical
scanning, sound waves travel through bones and tissue
and refiect back to draw a detailed picture of what's happening inside the body.
3. Nondestructive testing uses ultrasonic sound waves to detect.
in machines.
4. Much stronger ultrasound waves can be used to destroy problems in the human body, such as
kidney stones and tumors. These powerful waves make the stone or tumor
and then break apart.
a. These powerful ultrasound waves can also be used to

Answer
1. Sound waves that have frequencies too high to be detected by the human ear are known as ultrasonic waves.
2. In medical scanning, sound waves travel through bones and tissue and reflect back to draw a detailed picture of what's happening inside the body.
3. Nondestructive testing uses ultrasonic sound waves to detect flaws in machines.
4. Much stronger ultrasound waves can be used to destroy problems in the human body, such as kidney stones and tumors. These powerful waves make the stone or tumor vibrate and then break apart. These powerful ultrasound waves can also be used to clean items such as jewelry, false teeth, and machine parts.
5. SONAR, which is an abbreviation for sound navigation and ranging, is used by ships and submarines. They do this by sending sound waves to the bottom of the water and measuring how long it takes them to echo back.
