Ultrasonic sound waves are used for cleaning, echocardiography, ultrasonography, and removing kidney stones. Ultrasonic waves are high frequency sound waves that are above the range of human hearing. For cleaning, ultrasonic waves target a solution to powder contaminants. In echocardiography and ultrasonography, ultrasonic waves are used to take images of internal organs like the heart by reflecting off tissues of different densities to provide a clear picture. Kidney stone removal uses ultrasonic waves focused on the stone to break it up.

SOUND WAVES

6. • What does the figure indicates?
• Does any type of wave used
for the purpose?
• Which wave?

8. • What does the figure indicates?
• Name of the procedure?
• Does any wave used here?
• What’s the wave?
• Is the density of tissues in our internal organs be
same everywhere?
• So wouldn’t the waves hit such areas and be
reflected?
• So are we unlikely to get a clear image of them?
• Then explain how to take images of our
internal organs?
