One recent study has shown that x rays with a wavelength of 0.0050 nm can produce significant numbers of mutations in human cells.
1) Calculate the energy in eV of a photon of radiation with this wavelength.
2) Assuming that the bond energy holding together a water molecule is typical, estimate how many molecular bonds could be broken with this energy.
