JEE MainPhysicsAtoms and NucleiNumerical+4 / −1
The K α\alphaα X-ray of molybdenum has wavelength 0.071 nm. If the energy of a molybdenum atoms with a K electron knocked out is 27.5 keV, the energy of this atom when an L electron is knocked out will be ‾\underline{\hspace{2cm}}​ keV. (Round off to the nearest integer) [h = 4.14 ×\times× 10 −-− 15 eVs, c = 3 ×\times× 108 ms −-− 1]
