Molybdenum is frequently used as a target (anode) material to generate x-rays with characteristic wavelengths of Kα = 0.70930 Å, Kβ = 0.63229 Å.
a. Sketch a schematic diagram of the molybdenum x-ray emission spectrum. Identify all the main features and briefly explain their significance.
b. If the voltage (potential difference) accelerating electrons to the molybdenum target is increased, does this change the characteristic x-ray emission lines? Justify your answer.

X-ray filter
An X-ray beam from a tube with molybdenum anode (?=42) at an
acceleration voltage of ?=60 kV contains, besides the braking
continuum, a distinct ?? peak at 0.71 Å and a smaller ?? peak at
0.63 Å. To filter out the ?? line for diffraction experiments, a
zirconium filter (?=40) can be used. Justify this with the help of
Mosley's law and draw the X-ray spectrum of molybdenum superimposed
with the absorption effect of zirconium.
Is the main...
