Common miss
Direct answer
The common mistake is treating Which NDE method uses high-frequency sound to evaluate internal reflectors as a loose phrase instead of a rule, condition, or field decision with consequences. Ultrasonic testing introduces high-frequency sound and interprets reflections from internal interfaces or discontinuities. If you miss this area, review the explanation, tag the weak concept, and drill nearby topics such as Welding fundamentals, Inspection terminology, Welding symbol interpretation.
How to use this answer
Read the answer once, then prove it by choosing an answer in a practice question before looking at the explanation. If the miss repeats, tag the domain as NDE and drill a smaller set before returning to mixed practice.
