Hard X-rays for the study of fractures in bones should have a minimum wavelength of 10' m. The accelerating voltage for electrons in X-ray machine should be

< 124 kV

> 124 kV

between 60 kV and 70 kV

= 100 kV

Solution

< 124 kV

From conservation of energy the kinetic energy of electron equals the maximum photon energy (we neglect the he work function $ϕ$ because it is normally so small compared to eV_o).

eV_o= h v_max

${eV}_{o} = \frac{hc}{λ_{\min}} ∴ V_{o} = \frac{hc}{{eλ}_{\min}} \Rightarrow V_{o} = \frac{12400 \times 10^{- 10}}{10^{- 11}}$

= 124 kV

Hence, accelerating voltage for electrons in X-ray machine should be less than 124 kV.
