The intensity of X-rays from a coolidge tube is plotted against wavelength $\lambda$ as shown in figure. The minimum wavelength found is $\lambda_{c}$ and the wavelength of $K_{\alpha}$ like is $\lambda_{K}$. As the accelerating voltage is increased [image:11_image23.emf]

Question

(a) As accelerating voltage $V$ across $X$-rays tube increase, the value of minimum wavelength of $X$-rays, $\lambda_{c} = \frac{hc}{eV};$ decreases ; so the separation between $\lambda_{K}$ and $\lambda_{c}$ increases.
