Explain how defects in a metal block can be detected using ultrasound

Ultrasound is passed through one end of the metal and a detector is installed at the other end. When the metal is perfect, the ultrasonic waves travel as expected and hence are detected on the other end. For a metal with a defect, the waves are reflected back and hence don't reach the other end. When no detection is received, it can be concluded that the metal has a defect.

Hint: In order to answer this question, first we will explain how defects in a metal block can be detected using ultrasound and then we will discuss how ultrasound works. We will also discuss the other uses of ultrasound. Complete step by step solution: Metal blocks with flaws do not enable ultrasonography to flow through, therefore it is reflected. This fact is employed in the detection of flaws in metal blocks. Ultrasound is transmitted through one end of a metal block, while detectors are attached to the other. The metal block's faulty section prevents ultrasound from passing through. As a result, the detector will fail to detect it. As a result, ultrasonography can be used to detect faults in metal blocks. Or in simple words, when the metal is perfect, the ultrasonic waves travel as expected and hence are detected on the other end. For a metal with defects, the waves are reflected back and hence don't reach the other end. When no detections are received, it can be concluded that the metal has a defect. The sound waves are created by the transducer probe, which also receives the echoes. It functions as the ultrasound machine's mouth and ears. The piezoelectric (pressure electricity) effect, which was discovered by Pierre and Jacques Curie in 1880, is used by the transducer probe to generate and receive sound waves. Note: Sound waves are used in ultrasound imaging to create images of the inside of the body. Other uses of Ultrasound:- (i) It's used to figure out what's ca...

Defects in metal blocks do not allow ultrasound to pass through them and they are reflected back. This fact is used to detect defects in metal blocks. Ultrasound is passed through one end of a metal block and detectors are placed on the other end. The defective part of the metal block does not allow ultrasound to pass through it. As a result, it will not be detected by the detector. Hence, defects in metal blocks can be detected using ultrasound.
