Question

( When 50 kev electrons are made incident on a target material, the wavelength of kax-ray line was found to be 0.5 Å . when the accelerating potential is increased to looku, then the wavelength of Ka tine from the same target will be​

Answer 1

Answer:

we know that this transition energy will not change due to increase in accelerating potential so the wavelength of K alpha X ray remains the same

So wavelength is 0.5 Å

Explanation:

As we know that K-alpha X ray is characterstic X ray

this X ray is due to the transition of electron from n = 2 to n = 1

when high energy external electron strike out the electron of K shell then this vacancy is filled by electron of n = 2 shell

due to this transition the photon is released which is known as X ray of K alpha series

So here we know that this transition energy will not change due to increase in accelerating potential so the wavelength of K alpha X ray remains the same
