X-ray spectrometers often measure the energy of x-ray photons in units of kiloelectron volts (kev). this is the amount of energy gained by an electron after being accelerated by 1000 v of electricity. one kev is equivalent to 1.6 x 10-16 j. what is the wavelength of an x-ray from a phosphorous atom with an energy of 2.0 kev?
