The K shell ionization energies for Co, Cu and Molybdenum are 7.8,9 and 20.1 KeV. If an X-ray tube operates at 15 kV with any of the above metals as targets thenA. Characterstic x-rays of K series will be emitted only from CuB. Characterstic x-rays of K series will be emitted both from Cu and CoC.characterstic x-rays of K series will be emitted from Co,Cu and MolybdenumD. Shortest wavelength of continuous x-rays emitted is same for all three metals
