A potential difference of $15\text{ kV}$ speeds up the electrons. They then strike a metal target, and an X-ray spectrum is emitted.
(a(i))[3]
Explain why the X-ray photons have a continuous spread of energies.
(a(ii))[3]
Calculate the wavelength of the X-ray photon with the greatest energy produced.
(b(i))[2]
Determine the linear attenuation (absorption) coefficient $\mu$ for the X-ray beam in this tissue.
(b(ii))[2]
Determine the thickness of tissue that the X-ray beam must travel through for its intensity to drop to $5.0\%$ of its initial value.
