Industrial Applications of Ultrasonic Waves
Industrial Applications of Ultrasonic Waves
Use In Industries: Ultrasound is used in industry for detecting flaws (cracks, etc.) in metal blocks without damaging them. Metal blocks are used in the construction of big structures like bridges, machines and scientific equipment, etc. If there are some cracks and flaws in the metal blocks, which are invisible from outside reduces the strength of the structure. These can be detected by using ultrasound. This is based on the fact that an internal crack (or hole) does not allow ultrasound to pass through it. It reflects the ultrasound. Ultrasound waves are allowed to pass through one face of metal block (to be tested) and detectors are placed on the opposite face of the metal block to detect the transmitted ultrasound waves. If there is even a small defect, the ultrasound waves gets reflected back indicating the presence of the flaw or defect. Ultrasound reflected from a part of block, which shows that this metal block has a flaw or defect (like a crack) inside it. Ordinary sound waves cannot be used for detecting the flaws in metal blocks because they will bend around the corners of the defective location and therefore enter the detector.
Which of the following are correct : (a) Ultrasound reflected from a part of block, which shows that this metal block has a defect inside it. (b) Ordinary sound waves cannot be used for detecting the flaws in metal blocks. (c) Ordinary sound waves can be used for detecting the flaws in metal blocks | |||

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
