Consider a photon of continuous $X$-ray and a photon of characteristic $X$-ray of the same wavelength. Which of the following is different for the two photons?

Absorption of $X$-rays is maximum in which of the following different sheets?

The binding energy of the innermost electron in tungsten is $40 \, keV$. The energy of the characteristic $X$-rays emitted is:

An $X$-ray tube with a copper target emits a $Cu$ $K_{\alpha}$ line of wavelength $1.50 \ \mathring{A}$. What should be the minimum voltage through which electrons are to be accelerated to produce this wavelength of $X$-rays? $(h = 6.63 \times 10^{-34} \ \text{J}\cdot\text{s}, c = 3 \times 10^8 \ \text{m/s})$

If the $K_\alpha$ radiation of $Mo (Z=42)$ has a wavelength of $0.71 \;\mathring A$,calculate the wavelength of the corresponding $K_\alpha$ radiation of $Cu (Z=29)$ (in $\mathring A$). (in $.52$)

The continuous $X-$ray spectrum produced by an $X-$ray machine at constant voltage has
