Question

X ray with lowest energy is
A. k alpha
B. k beta
C. k gamma
D. L alpha​

Answer 1

Answer:

X-rays with energies between 10 keV and a few hundred keV are considered hard X-rays. There is no sharp distinction between the highest energy X-rays and the lowest energy gamma rays.

Answer 2

Answer:

L alpha

Explanation:

the transition from L M and N shell give rise to K alpha and K beta and K gamma rays respectively.These rays are of high energy.SIMILARLY,  L,M and N series characteristic x rays RELATIVELY LOW ENERGY are produced due to ejection of electrons from L M and N shells respectively produce L alpha L beta M alpha M beta etc.
