The minimum wavelength of X-rays produced by an electron accelerated through a potential difference of \( V \) volts is proportional to:

  1. A
    \( \frac{1}{V} \)
  2. B
    \( \sqrt{V} \)
  3. C
    \( \frac{1}{\sqrt{V}} \)
  4. D
    \( V^2 \)
View Answer & Solution

Correct answer · Option A

\( \frac{1}{V} \)

Explanation

Minimum wavelength \( \lambda_{\min} = \frac{hc}{eV} \), which implies \( \lambda_{\min} \propto \frac{1}{V} \).
