1) A certain medical machine emits x-rays with a minimumwavelength of 0.025 nm. One day, the machine has an electricalproblem and the voltage applied to the x-ray tube decreases to 74%of its normal value. Now what is the minimum x-ray wavelengthproduced by the machine?
?min = _________ nm
2) What is the maximum x-ray energy this machine (withelectrical problems) can produce?
Emax = _________ eV
3) The atomic number of an element is 82. According to the Bohrmodel, what is the energy of a K? x-ray photon?
E = ___________ eV
