Question
Mark the CORRECT option(s) : -
Options
A.When an electron is knockout from an atom then it has smaller energy than a neutral atom.
B.K X-ray is emitted when a hole makes a jump from the K shell to some other shell.
C.The wavelength of K X-ray is smaller than the wavelength of L X-ray of the same material.
D.The wavelength of Kα X-ray is smaller than the wavelength of Kβ X-ray of the same material.
Solution
Jumping of electrons to K shell causes K X-ray excision. As electron is knocked out the bidden electron having -ve energy is lost, hence the residual atom has larger energy.
