Question

Can Lα X-ray of one material have shorter wavelength than Kα X-ray of another?

Answer 1

Explanation:

• There will be an emission of Lα X-ray when there is jumping of the electron to the L shell from the M shell.

• There is an involvement of less energy when there is a jumping of electron to the L shell from the M shell. This is lesser than the energy that is generated when the energy jumps to the K shell from the L shell.

• And, the photon’s wavelength is inversely related to the energy. So, Kα X-ray has the lesser wavelength than Lα X-ray for the same material.
