The wavelength of `K_(alpha)` X-ray of tungsten is 21.3 pm. It takes 11.3 keV to knock out an electron from the L shell ofa tungsten atom. What should be the minimum accelerating voltage across an X-ray tube having tungsten target which allows production of `k_(alpha)` X-ray ?

The wavelength of K_alpha X-ray of tungsten is 21*3 pm. It takes 11*3 keV to knock out an electron from the L shell of a tungsten atom. What shoulb be the minimum accelerating voltage across an X-ray tube having trungsten target which allows production of K_alpha X-ray?

The wavelength of K_(alpha) X-ray for an element is 21.3 pm. It takes 11.3 ke V to knock out an electron from the L-shell of the atom of the element. What should be the minimum accelerating voltage across on X-ray tube having the element as target which allows production of K_(alpha) X-ray?

The wavelength of K_(alpha) X-ray for an element is 21.3 pm. It takes 12.5 ke V to knock out an electron out an electron from the L-shell of the atom of the element. What should be the minimum accelerating voltage across on X-ray tube having the element as target which allows production of K_(alpha) X-ray?

The wavelength for k_(beta) x-ray of certain ,material A is 15.53pm .If takes 10KeV to , remove an electron from M - shell of A ., What is the minimum accelerating , potential that should be applied across , the x -ray tube with target material A .So , that a k_(beta) x-ray would be produced?

The wavelength for k_(beta) x-ray of certain, material A is 15.53 pm .If takes 10KeV to remove an electron from M - shell of A .What is the minimum accelerating potential that should be applied across the x -ray tube with target material A . So that a k_(beta) x -ray would be produced? Express answer in powers of 10^(4) ? (Take h=1242ev-nm )

The wave length of Kbeta X-ray of certain metal is 12.42 pm . It takes 10Kev to remove the electron from M shell of an atom of that metal the minimum accelerating voltage that should be applied across the X-ray tube , so that a K_(a) X-ray would be produced is ( hc=1242eVnm )
