Dual Nature Of Light Question 520
Question: The minimum wavelength of X-ray emitted by X-rays tube is 0.4125 Å. The accelerating voltage is [BHU 2003; CPMT 2004; MP PMT 2005]
Options:
A) 30 kV
B) 50 kV
C) 80 kV
D) 60 kV
Show Answer
Answer:
Correct Answer: A
Solution:
$ {\lambda_{\min }}=\frac{12375}{V}{\AA},\Rightarrow ,V=\frac{12375}{0.4125}=30,kV $
