Question
The potential difference applied to an X - ray tube is increase. As a result, in the emitted radiation
Options
A.The intensity increases
B.The minimum wavelength increases
C.The intensity decreases
D.The minimum wavelength decreases
Solution
λmin ∝ 
if V ↑ then (λmin) ↓
No. of collision per electron increases then intensity increases
if V ↑ then (λmin) ↓No. of collision per electron increases then intensity increases
