The minimum wavelength of X-ray emitted by X-ray tube is 0.4125A˚0.4125 Å. The accelerating voltage is

Options

  1. A30 kV
  2. B50 kV
  3. C80 kV
  4. D60 kV

Correct answer

A. 30 kV

Step-by-step solution

From the formula eV=hcλV=hceλ=6.6×10−34×3×1081.6×10−19×0.4125×10−10=30×103 volt =30kvolt\begin{aligned} e V & =h \frac{c}{\lambda} \\ V & =\frac{h c}{e \lambda}=\frac{6.6 \times 10^{-34} \times 3 \times 10^8}{1.6 \times 10^{-19} \times 0.4125 \times 10^{-10}} \\ & =30 \times 10^3 \text{ volt }=30 \mathrm{kvolt}\end{aligned}
