For copper, the transition 2p→1s transition is known as______

For copper, the transition 2p→1s transition is known as______ Correct Answer Kα

For copper, the transition 2p→1s, is called Kα, has a wavelength of 1.5418 A˚ and 3p→1s transition, Kβ, 1.3922 A˚. The Kα transition occurs much more frequently than the Kβ and it is these more intense Kα radiations which results that is used in diffraction experiments.
