Question
Explain how defects in a metal block can be detected using ultrasound.
Answer
Ultrasounds can be used to detect cracks and flaws in metal blocks. Ultrasound waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of the flaw or defect.
