Ultrasound is also useful for __________ i. detecting fault in metal sheets ii. imaging marine depths iii. looking for metals beneath the earth’s surface iv. detecting distances v. detecting earthquakes

Ultrasound is also useful for __________ i. detecting fault in metal sheets ii. imaging marine depths iii. looking for metals beneath the earth’s surface iv. detecting distances v. detecting earthquakes Correct Answer i, ii, iv

Ultrasound is used for detecting the fault in metal sheets, imaging marine depths and detecting distances. If the metal sheets have faults like cracks or deformity, the reflected sound waves will not be uniform. SONAR and RADAR are used to detect distances and work on the principle of ultrasound.
