Ultrasound has a wide range of applications in science and technology, industrial and agricultural production, medical and health care, etc., the use of the principle of echolocation can detect the depth of the ocean, drawing Sonar devices can use the principle of echolocation can detect the depth of the ocean, drawing thousands of meters underwater topographic maps;

Because of the strong penetrating ability of ultrasound, medicine can be used to detect the body inside the disease cover;

In the typhoons, tsunamis will produce infrasound;

Therefore, the answer is: sonar, strong penetration, typhoons, tsunamis.
