Question
When X-rays tube is operated at V0 voltage, it produces Kα X-ray of wavelength λ. Now voltage is made 
then wavelength of Kα X-ray from the tube will be :-
then wavelength of Kα X-ray from the tube will be :-Options
A.λ
B.10λ
C.0.1 λ
D.0.01 λ
Solution
wavelength of Kα X ray is constant at lower potential only intensity can be changed.
