For the production of characteristic\[+10.0\,\,V\]the electron transition is:                       [BHU PMT-2002]

A)                  \[-10.0\,\,V\]                   

B)                  \[+2.5\,\,V\]

C)                  \[-2.5\,\,V\]                     

D)                  \[10\mu F\]

Correct Answer: A

Solution :

                 Electrons transitions to lower atomic levels in heavy atoms have quantum energies which place them in the X-ray region of the electromagnetic spectrum. The X-ray emissions associated with these transitions are characteristic X-ray. As is clear from the diagram\[\frac{{{f}_{t}}}{15}=\frac{1.5-1}{\left( \frac{1.5}{4/3}-1 \right)}=\frac{0.5}{0.125}\], is from\[\Rightarrow \].
