Vedclass · Answer

(C) The minimum wavelength $(\lambda_{\min})$ of $X$-rays produced by an $X$-ray tube is given by the Duane-Hunt law:$\lambda_{\min} = \frac{hc}{eV} = \frac{12400 	ext{ } \mathring{A} \cdot V}{V}$Given $\lambda_{\min} = 0.45 \mathring{A}$.Substituting the value into the formula:$0.45 = \frac{12400}{V}$$V = \frac{12400}{0.45}$$V \approx 27555 	ext{ } V$Comparing this with the given options, the closest value is $27500 	ext{ } V$.
