Please answer these questions in as much details as possible please and thank you in advance figure 3 is the first picture and second is figure 4

7. An X-ray tube emission spectrum is shown in Figure 3 on page 5. a) What is an approximate wavelength of the X-ray photon corresponding to the Ka peak of the characteristic radiation? 1 pm = 1012 m. b) Find the energy of an X-ray photon with the wavelength found in part a). 8. What is the photoelectric absorption and Compton scattering of X-rays in tissues? 9. Write the mathematical relation between the intensity of transmitted X-rays and the tissue thickness? Explain the quantities appearing in this relation. 10. The plot of the counting rate of the transmitted X-rays versus the tissue thickness is shown in Figure 4 on page 6. a) What is the coefficient of attenuation in this case? b) Calculate the numerical value of transmittance if the tissue thickness is x = 2 mm.
