You are trying to identify some elements by using Moseley approach i.e.
by observing their characteristic X-ray spectrum. Upon experience, you
understood that your setup and the elements you are interested gives only
one characteristic X-ray line which are called L series and specifically an
La line.
a. Derive a Moseley-like expression for La lines by using Bohr's
assumptions.
b. Choose a suitable element from the Periodic table and calculate the
characteristic X-ray emission wavelength.
