Dual Nature Of Light Question 525
Question: If the minimum wavelength obtained in an X-ray tube is $ 2.5\times {{10}^{-10}}m $ , the operating potential of the tube will be [RPMT 2003]
Options:
A) 2 kV
B) 3 kV
C) 4 kV
D) 5 kV
Show Answer
Answer:
Correct Answer: D
Solution:
$ {\lambda_{\min }}=\frac{12375}{V}{\AA} $
$ \Rightarrow V=\frac{12375}{2.5} $ = 4950 V ≃ 5 kV.
