(a(i))[3]
Explain why the wavelength distribution is continuous.
(a(ii))[2]
Explain why there is a sharp cut-off at short wavelength.
(a(iii))[1]
Explain why a series of peaks is superimposed on the continuous wavelength distribution.
(b(i))[1]
In X-ray imaging of body structures, longer wavelength photons are often removed from the X-ray beam. State how this filtering is achieved.
(b(ii))[1]
Suggest why this filtering is used.
(ii)[1]
Suggest why this filtering is applied.
