Ultrasound and its applications
In this Class 9 Science topic from the chapter “Sound Waves: Characteristics and Applications,” students learn that ultrasound consists of sound waves with frequencies higher than the human hearing range. They explore how such waves are produced, transmitted and detected, and understand applications including medical ultrasonography, SONAR for measuring depth and locating objects underwater, industrial testing, and cleaning delicate equipment. The topic also connects frequency and wave behaviour with the practical uses and limitations of ultrasound.
