For what thickness of a material, do the X-rays give the best results?(a) 50 mm(b) 55 mm(c) 60 mm(d) 65 mm |

Answer» Right option is (a) 50 mm To elaborate: X-rays are considered to be having a larger wavelength as compared to that of gamma rays. Owing to this fact, the penetration power of the X-rays is less. Hence, for a shorter thickness, it would give good detection. The best results are obtained in X-ray detection when the thickness of the material is below 50mm. |
