How are X-rays produced? Give any two uses of these.
Answer: Fast electrons decelerated on a metal target; uses: medical imaging, flaw detection.
Solution
Production: X-rays are produced when fast-moving electrons, accelerated through a high potential difference, strike a heavy metal target (such as tungsten) and are suddenly decelerated; the lost energy is radiated as X-rays.
Two uses: (i) medical radiography — imaging bones and detecting fractures; (ii) industrial inspection — detecting flaws, cracks and defects in metal castings and welds (also security scanning).
