JEE PYQ: Nuclear Physics Question 6
Question 6 - 2021 (24 Feb Shift 2)
An X-ray tube is operated at 1.24 million volt. The shortest wavelength of the produced photon will be:
(1) $10^{-3}$ nm
(2) $10^{-2}$ nm
(3) $10^{-1}$ nm
(4) $10^{-4}$ nm
Show Answer
Answer: (2)
Solution
$\lambda_{\min} = \frac{hc}{eV}$ $\lambda_{\min} = \frac{12400 \text{ eV} \cdot \text{\AA}}{1.24 \times 10^6 \text{ eV}}$ $\lambda_{\min} = 10^{-2}$ nm
