7) A diffractometer pattern was recorded from a strained aluminum sample (FCC, a 4.05 A) using CuKa x-rays (λ-1 .542 A). If the broadening (FWHM) of the { 331 } reflection was measured to be 1°, what is the magnitude of microstrain in the Al sample? 7) A diffractometer pattern was recorded from a strained aluminum sample (FCC, a 4.05 A) using CuKa x-rays (λ-1 .542 A).

Bnefly, but informatively, describe how X-rays are generated for analytical purposes 147 Bnefly, but informatively, describe how X-ray radiation is detected. [4]
(i) How are X-rays produced and modified for imaging. (ii) How are X-rays used in imaging internal body structure. Please help answer theses two question.
(a) What is the physical difference between X- rays, y -rays, light and radio waves? How do they interact with tissue (in the absence of a magnetic field)? (b) Draw the X-ray tube spectrum, i.e., the intensity distribution of X-rays as a function of the frequency of emitted X-ray photons (1) at the exit of the X-ray tube before any filtering takes place, and (2) after the filter but before the X-rays have reached the patient. (c) How does the...
9. The diagram below shows a few parallel light rays passing from one material into a different material. Material 2 Material a) In which material does the light travel faster, or docs it travel the same speed in both? How do you know? both? How do you know? both? How do you know? your answers to a-c. (Review the PhET Bending Light simulation if you are confused about b) In which material does the light have a shorter wavelength, or...
Question5 micro infra visible waves -red gamma X-rays rays B C D The diagram represents the range of waves in the electromagnetic spectrum. a) What are the waves in section D called? b Give one important use for these waves. c) State one hazard of exposure to these waves. d) Explain one precaution that can be taken to minimize this hazard (Total: 4 marks) (Total marks for TMA-36)
gamma -rays are generated when An electron is knocked out of its orbit by a photon with high energy The nucleus undergoes a change in its energy state. A neutron is com energy into a proton. At alpha-particle b emitted. An. X-ray interacts with an electron.
With the aid of a suitable diagram explain how a thin film of refractive index n can be used as an anti-reflective coating on a glass lens with refractive index ng.
A nucleus of an atom shows the following energy diagram. How many emissions gamma rays lines are possible? List the transitions in KeV units. Explain. _________________________ 300 keV _________________________ 200 keV __________________________ 80 keV __________________________ 0 keV
